Answer:
![\boxed{ \bold{ \boxed{ \sf{1. \: \: \: \: \: x = 12}}}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/96njw9ckp8skq2fqmvukg41xq08ybwqp4t.png)
![\boxed{ \bold{ \boxed{ \sf{2. \: \: \: \: \: x = 3}}}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/d3vjfh7cd4atu28p7l6r42u4vfk85l2tkn.png)
Explanation:
![\sf{1. \: \: \: \: (x)/(3) + 2 = (x)/(4) + 3}](https://img.qammunity.org/2021/formulas/mathematics/high-school/damwgm9e2462xndteiumdv0b7nws28cih4.png)
Move x / 4 to left hand side and change its sign
Similarly, move 2 to right hand side and change it's sign
![\longrightarrow{ \sf{ (x)/(3) - (x)/(4) = 3 - 2}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/2z424grfs20h3x4h8252drm32lmyc5j04v.png)
Take the L.C.M of 3 and 4
L.C.M of 3 and 4 = 12
![\longrightarrow{ \sf{ (x * 4 - x * 3)/(12) = 3 - 2}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/myl17gsv9ubskmgo2e4n9e0uuuna0raos4.png)
![\longrightarrow{ \sf{ (4x - 3x)/(12) = 3 - 2}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/dmpyzwjaqjgdx1260l7szweot1p5dnal2k.png)
![\longrightarrow{ \sf{ (x)/(12) = 3 - 2}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/otv1c8alpxbf6up2eg9ok2sl9kdwz15va6.png)
Subtract 2 from 3
![\longrightarrow{ \sf{ (x)/(12) = 1}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/nkfwgnl2ddjh88qswi5g2njzeps04ee68g.png)
Do cross multiplication
![\longrightarrow{ \sf{x = 1 * 12}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/7n6nq75cegfzsbfchbfxnvu0nneov675kh.png)
![\longrightarrow { \sf{x = 12}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/pt3dttzh361p3lnwblxcasowf4bnug3f2l.png)
--------------------------------------------------------------------
![\sf{2. \: \: \: \: 3(4 + 2x) = 33 - x }](https://img.qammunity.org/2021/formulas/mathematics/high-school/ucu0mqq5oro76fiy27hjz4kq8a9xtcbqpf.png)
Distribute 3 through the parentheses
![\longrightarrow{ \sf{12 + 6x = 33 - x}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/u8tr28yfxk7z9p1tfttp3jrt4ig1bajoo6.png)
Move x to left hand side and change it's sign
Similarly, move 12 to right hand side and change it's sign
![\longrightarrow{ \sf{6x + x = 33 - 12}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/1ggdrt5qfh8n6bawhm8365sn049hlncpv7.png)
Collect like terms
![\longrightarrow{ \sf{7x = 33 - 12}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/igu5057tl16eh3b47t0ahc46nwgn4czmmx.png)
Subtract 12 from 33
![\longrightarrow{ \sf{7x = 21}}](https://img.qammunity.org/2021/formulas/mathematics/high-school/tq5sbp181ckntt6wviy5blpb1mdp6w7667.png)
Divide both sides by 7
![\longrightarrow{ \sf{ (7x)/(7) = (21)/(7) }}](https://img.qammunity.org/2021/formulas/mathematics/high-school/29buhw18byhs0al4t1zswtj2sd6hh7230g.png)
Calculate
