One Step Solve Equations

How do we solve an algebraic equation?

• We do the opposite operation on BOTH sides of the equation.

• We do the same operation on both sides of the equation.

• We do the opposite operation on only 1 side of the equation.

• We don't.

What needs to be done to solve this equation?

• subtract both sides by 4.

• cross out the 4.

• multiply both sides by 4.

• divide both sides by 4.

What needs to be done to solve this equation?

z - 5 = 20

• subtract both sides by 5.

• add five to both sides.

• cross out the 5.

• add five on the left side of the equation.

How would we solve the following equation?

x + 3 = 10

• subtract 3 only on the left side of the equation.

• cross out the three.

• Subtract three on both sides of the equation.

• add three on both sides of the equation.

x + 12 = 20

• x = 32

• x = -32

• x = 8

• x = -8
