Answer:

x= 3 y=5

Explanation:

solving for x

5x + 3y = 15 Zero out the substitute

5x +( 3y * 0) = 15

5x + 0 = 15 Adding by zero can be ommited

5x = 15 Divide both side by 5

x = 3

if solving for y

5x + 3y = 15

(5x*0) + 3y = 15 zero out the substitute

0 + 3y = 15

3y = 15 devide by the number in front of x

y= 5
