-5y%2B6=-1%28y-7%29 Start with the given equation



-5y%2B6=-y%2B7 Distribute the negative


-5y%2B6=-y%2B7 Combine like terms on the right side


-5y=-y%2B7-6Subtract 6 from both sides


-5y%2By=7-6 Add y to both sides


-4y=7-6 Combine like terms on the left side


-4y=1 Combine like terms on the right side


y=%281%29%2F%28-4%29 Divide both sides by -4 to isolate y



y=-1%2F4 Reduce

--------------------------------------------------------------
Answer:
So our answer is y=-1%2F4 (which is approximately y=-0.25 in decimal form)



So the answer is C)
