First you subtract 9x from y and you get 45 - 9x = -y and you don't want negatives so you switch all the signs to get y = -45 + 9x

Answer:

y=9x-45

Explanation:

Given:
9x-y=45

We are given an equation of x and y. We need to solve for y.

It means to isolate variable y. We have to move all variable and constant right side and leave y at left side.


9x-y=45

Subtract 9x both sides (Subtraction property of equality)


9x-9x-y=-9x+45

cancel like term


-y=-9x+45

Divide each side by -1 (Division property of equality)


y=9x-45

Hence, The equation solve for y=9x-45
