Question

3x+2=2x+7 solve for x pls it homework due for tomorrow

Answer 1

× = 5

Explanation:

3x + 2 = 2x + 7

x + 2 = 7

x = 5

Answer 2

• 2.5

`\:`

Given Equation,

`\\ {\longrightarrow{ \qquad{{ {\pmb{\rm { 3x+2=2x+7}}}}}}} \\ \\`

Subtracting 2 from both sides we get :

`\\ {\longrightarrow{ \qquad{{ {\pmb{\rm { 4x+2 - 2=2x+7-2}}}}}}} \\ \\`

`{\longrightarrow{ \qquad{{ {\pmb{\rm { 4x=2x+5}}}}}}} \\ \\`

Subtracting 2x from both sides we get :

`\\ {\longrightarrow{ \qquad{{ {\pmb{\rm { 4x-2x=2x+5-2x}}}}}}} \\ \\`

`{\longrightarrow{ \qquad{{ {\pmb{\rm { 2x=5}}}}}}} \\ \\`

Dividing 2 from both sides we get :

`\\ {\longrightarrow{ \qquad{{ {\pmb{\rm { (2x)/(2) = (5)/(2) }}}}}}} \\ \\`

`{\longrightarrow{ \qquad{{ {\pmb{\frak {x = 2.5 }}}}}}} \\ \\`

Therefore,

• The value of x is 2.5
