Practice (Combining like terms & distributive property)

What is the objective when solving an equation

• Guess and check

• Combine like terms

• Isolate the variable

• Distributive property

Solve for y: -8 = 3y + 6 + 4y - 7

• y = -1

• y = 1

• y = -8

• y = 7

Solve for a: 3(a + 4) - 2a = -4

• a = 16

• a = -8

• a = -16

• a = -2/5

Solve for x: 2x - 3 + 4x = 27

• x = 12

• x = 5

• x = 4

• x = 15

Solve for x: - (x - 8) = -1 - 1

• x = 6

• x = - 6

• x = 10

• x = - 10

What is the FIRST step in solving this equation:

2x - 4(x - 5) =10

• Add 4 to both sides

• Distribute 4 to x and - 5

• Add the 2x and x

• Distribute -4 to x and -5

Solve for y: -2 + 12 = -8y - 50 + 3y

• y = - 8

• y = - 12

• y = 8

• y = 12

Solve for x: 3(x - 6) + 2x = 22

• x = 2

• x = 3

• x = 18

• x = 8

Solve for the equation: 2x + 3(5x - 7) = 47

• x = 1

• x = 3

• x = 2

• x = 4

Solve for n: 21 = 3 + 4a + 5a

• n = 9

• n = 6

• n = -7

• n = 2
