Algebra Solving Equations Involving Like Terms

What should you do first when solving equations?

• Distributive Property

• Combine like terms

• Isolate the variable

• Whatever you do to one side do to the other.

Like terms must have _____________________________________ and _________________________.

• same variable and same power or exponent

• same variable and number

• exponent and number

• same variable and the same sign

• divide both sides by 17

Solve for X. 3x + 15 - 7x = -7

• x = 2

• x =-4/5

• x = -2

• x = 5 1/2

Solve for X. 4 + x - 17 = 22

• x = -35

• x = 35

• x = 1

• x = 9

-8 = -(2x + 4)

• x = -2

• x = 2

• x = 6

• x = -6

Solve the equation.

3(3x - 6) = 18

• x = 4

• x = -4

• x = 0

• x = -12

Solve the equation.

3x + 2(4x - 4) = 3

• x = 4

• x = 3

• x = 2

• x = 1

Solve the equation.

-11 + 3(b + 5) = 7

• b = 1

• b = -1

• b = 3

• b = -3
