7=2x + 15 2x= -8 x= -4
<span>8= 3x 8= 3x+0 3x +-8 3(-4) +-8 -12 - 8 </span>
<span>Final Answer -20</span>
Simplify 9 - 7x - 7x to 2 - 14x
2 - 14x = 4
Subtract 2 from both sides
-14x = 4 - 2
Simplify 4 - 2 to 2
-14x = 2
Divide both sides by -14
x = -2/14
Simplify 2/14 to 1/7
x = -1/7

Answer:
16
Step-by-step explanation:
you replace the letter with the number given to replace them. So, in the equation you replace the letter C with -1, as it tell you on the side. You do the same with F, but with 3. your equation should look like: 7(-1 + 5) - 3 × 4. you then solve from there and should get 16. I hope this is right, if not my bad
