Hello from MrBillDoesMath!

Answer:

1. 1

2. -13/7

Discussion:

1. 2x + 4(3-2x) = 3( 2x + 2)/6 + 4 => as 3(2x+2) = 6x + 6

2x + 4(3-2x) = (6x + 6)/6 + 4 => (6x + 6)/6 = x + 1

2x + 12 - 8x = x + 1 + 4 => combine x terms on lhs

-6x + 12 = x + 5 => subtract x from both sides

-7x + 12 = 5 => subtract 5 from both sides

-7x + 12 -5 = 0 =>

-7x + 7 = 0

x = 1


2. 4z + 5 = -3z - 8 => add 3z to both sides

4z + 3z + 5 = -8 => subtract 5 from both sides

7z = -8 -5 = -13 => divide both sides by 7

z = -13/7

Thank you,

MrB
