20 - (y-10) - 41 = 180

what's y?

y = - 191

Step-by-step explanation:

to find y we must isolate it through algebraic manipulation

20 - (y-10) - 41 = 180

-21 - (y-10) = 180 (add like terms)

- (y-10) = 201 (add 21 to both sides)

y-10 = - 201 (divide both sides by - 1)

y = - 191 (add 10 to both sides)

y = - 191

20 - (-191-10) - 41=180
