Answer:
x = 10
Step-by-step explanation:
-8(-3 + x) = -56
Distribute the -8 into the (-3 + x).
24 - 8x = -56
Subtract 24 from both sides.
-8x = -80
Divide both sides by -8.
x = 10.
Proof:
-8(-3 + x) = -56
Substitute variable.
-8(-3 + 10) = -56
Add inside parenthesis.
-8(7) = -56
Multiply.
-56 = -56
Normally two. However, one is often extraneous.
-⅔ (6x + 9) = 18
Apply distributive property. Multipy -⅔ to 6x and 9.
-4x - 6 = 18
Add 6 to both sides so -4x can be alone.
-4x - 6 + 6 = 18 + 6
-4x = 24
To get x alone, divide both sides by -4.
-4/-4x = 24/-4
x = -6
x = -6 is your answer. I hope this helps! Let me know if you need more help or if I got something wrong.
