Question

9x - y = 45 solve for y

Answer 1

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 2

Answer:

y=9x-45

Step-by-step 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
