Answer:
5(2x + 3) = − 2x - (4 - 3x)
10x +15 = -2x - (4 - 3x)
10x + 15 = 2x - (4 - 3x)
10x + 15 = -2x - (-3x +4)
10x +15 = -2x + 3x - 4
combine like terms:
10x + 15 = -2x + 3x - 4
10x+ 15 = 1x - 4
multiply by 1
10x + 15 = 1x - 4
10x + 15 = x - 1
Subtract 15 from both sides
10x + 15 = x - 4
10x + 15-15 = x - 4 - 15
simplify
(subtract the numbers first) 10x 15-15 = x - 4 - 15
10x = x - 4 -15
10x = x-4-15
10x = 19
Subtract x from both sides
9x = -19
9x/9 = -19/9
SIMPLIFY
x = 19/9
