Which inverse operation do you perform first when solving the equation 12=10−3x

12 = 10 − 3 x?

Which inverse operation do you perform last when solving the equation 35x−12=18

First Operation Performed - Subtract 10

12 = 10 - 3x \\ (12 - 10) = (10 - 10) - 3x

Last Operation - Divide by 3

(3)/(5)x - 12 = 18 \\ (3)/(5) x = 30 \\ (3x)/(5) = 30 \\ 3x = 150 \\ x = (150)/(3)
