Solve -3+7y=5x+2y when x=-5

y = -22/5

Step-by-step explanation:

-3+7y=5x+2y

Subtract 2y from each side

-3+7y-2y=5x+2y-2y

-3 +5y = 5x

Add 5 to each side

5y = 5x+3

Divide each side by 5

y = 5x/5 +3/5

y = x +3/5

Let x = -5

y = -5 + 3/5

y = -25/5 +3/5

y = -22/5

Step-by-step explanation:

Replace:

Subtract -2y

Add 3

Combine like terms;

Divide by 5.

Proof

To make it easier to solve, add 154/5

Now add 25
