Rules, Equations and Graphs

Solve the equation for n. 8n = 16

• n = 24

• n = 32

• n = -2

• n = 2

Simplify the expression: 5(3x + 1)

• 15x + 1

• 15x + 5

• 8x + 1

• 8x + 6

Solve for p:

• p = 3

• p = 48

• p = 16

• p = 12

Solve: 3(x - 2) = 18

• x = 6.7

• x = -4

• x = 4

• x = 8

What is the best first step to solve for n in the following equation: 3n - 7 = 30.

• Divide 3n by 3

• Subtract 7 from both sides

• Subtract 30 from both sides

• Add 7 to both sides

Find the error in the problem below:19 - 2k = 3k - 1 +3k +3k19 + 1k = -1-19 -19 k = -20

• They should have divided by 1 in the last step

• They should add 19 instead of subtracting 19

• They should have subtracted 3k instead of adding 3k

• There is no error

Solve the following equation: 5x - 3 + 2x = x + 7 + 6x

• x = -2.5

• x = 7

• No solution

• Any Number

Solve the following equation: -(x+3) =2x - 6

• x = 3

• x = 1

• No solution

• Any Number

Simplify the expression: 4 - (2x + 3) - (x + 1)

• -3x
