Answer: x = 7, y = -3

Step-by-step explanation:

3y = 26 - 5x --> added 5x to both sides to get: 5x + 3y = 26

Elimination method (I am going to eliminate "x":

5x + 3y = 26 → 6(5x + 3y = 26) → 30x + 18y = 156

6x + 7y = 21 → -5(6x + 7y = 21) → -30x - 35y = -105

-17y = 51

÷-17 ÷-17

y = -3

Now, input y = -3 into one of the original equations to solve for "x":

3y = 26 - 5x

3(-3) = 26 - 5x

-9 = 26 - 5x

-9 -26 = -5x

-35 = -5x

7 = x
