Answer:

D.) 12

Step-by-step explanation:

16x - 3(4x + 5) = 2x + 9

16x - 12x - 15 = 2x + 9

4x - 2x = 15 + 9

2x = 24

2x/2 = 24/2

x = 12

Check:

16x - 3(4x + 5) = 2x + 9

16(12) - 3(4(12) + 5) = 2(12) + 9

192 - 3(48 + 5) = 2(12) + 9

192 - 3(53) = 24 + 9

192 - 159 = 33

33 = 33

rjkz [21]

Answer:

$x=-\frac{15}{8}$

Step-by-step explanation:

$x+7=-7x-8$

Add 7x to both sides:

$8x+7=-8$

Subtract 7 from both sides:

$8x=-15$

Divide both sides by 8:

$x=-\frac{15}{8}$
