X = -16
Step-by-step explanation:
Combine the like terms which are -7x & -11x
-18x-224=64
Then you add 224 to both sides
-18x-224 + 224 = 64 +224
Cancel out the -244+244 so you only do 64 + 224
-18x = 224
Divide both sides by -18
-18x/-18 =288/-18
Cancel out the one with the same denominator & numerator
288/-18
You answer should be -16 hope that helps
