9y-1-7y=7-6y-15 Start with the given equation


2y-1=7-6y-15 Combine like terms on the left side


2y-1=-6y-8 Combine like terms on the right side


2y=-6y-8%2B1Add 1 to both sides


2y%2B6y=-8%2B1 Add 6y to both sides


8y=-8%2B1 Combine like terms on the left side


8y=-7 Combine like terms on the right side


y=%28-7%29%2F%288%29 Divide both sides by 8 to isolate y


--------------------------------------------------------------
Answer:
So our answer is y=%28-7%29%2F%288%29 (which is y=-0.875 in decimal form)
