Grade 8 Linear Equations Quiz

Solve the equation: 3x = 15

• x = 3

• x = 10

• x = 7

• x = 5

Solve the equation: 2y + 5 = 11

• y = 2

• y = 3

• y = 7

• y = 5

Use inverse operations to solve the equation: 4a - 7 = 25

• a = 8

• a = 12

• a = 10

• a = 5

Use inverse operations to solve the equation: 3b + 8 = 20

• b = 10

• b = 6

• b = 4

• b = 12

Solve the equation with variables on both sides: 2x + 5 = 3x - 2

• x = 10

• x = -5

• x = 4

• x = 7

Solve the equation with variables on both sides: 4y - 7 = 2y + 5

• y = 3

• y = -2

• y = 10

• y = 6

Apply the distributive property to solve the equation: 3(x + 4) = 15

• 3x + 12 = 15

• x + 12 = 15

• 3x + 4 = 15

• x + 4 = 15

Apply the distributive property to solve the equation: 2(2y - 3) = 10

• y = 10

• y = 2

• y = 5

• y = 4

Solve the equation with fractions: 1/2x = 3

• x = 6

• x = 2/3

• x = 1/6

• x = 3

Solve the equation with fractions: 3/4y + 2 = 5

• 1/2

• 7

• 3/5

• 2
