2x + 3y = 5x - y First combine like terms, so add y on both sides
2x + 3y + y = 5x - y + y
2x + 4y = 5x Subtract 2x on both sides
4y = 3x
Now you need to find the missing value x. Since they gave you y = 0, you can plug in 0 into y in the equation
4(0) = 3x
0 = 3x Divide 3 on both sides
0 = x ----------> (0, 0)
