My last one for tonight .. #catchinguponworksolving equations with two variables example solve x + y = 6 if x = 3 x + y = 6 3 + y = 6 3 + 3 = 6 y = 3 another example solve y - x = 2. if x = 9 y - x = 2 y - 9 = 2 11 - 9 = 2 y = 11 first question solve each equation if x = 5 1. 1 = y - x 2. x ÷ 5 = y 3. 5x = y 4. y ÷ x = 7 5. xy= 20 6. x = 2 + y 7. 9 - y = xsolve each equations if y = 10 1. x - y = 4 2. y ÷ 2 = x 3. 5y = x 4. y - 3 = x 5. 3y = x 6. y + 3 = x 7. x ÷ 9 = y 8. y - x = 0
