Equation v Expression

Mathematically, what is the 10 doing to the x?

10x = 90

• Adding 10

• Subtracting 10

• Multiplying 10

• Dividing 10

Simplify the following expression:
-10x + 15 - 3x + 2

• 13x² + 17

• -13x² + 13

• -13x + 17

• -7x + 17

Solve:
-19 + 3x = 3( x - 5)

• No Solutions

• Many Solutions

• x = (-6)

• x = 8

Solve the equation: 
x + 7 = 12

• x = 5

• x = 19

• x = -5

• x = 84

Solve the equation:
x - 2.6 = -4.6

• x = 2

• x = -2

• x = 7.2

• x = -7.2

What is the first step in solving the following equation?
3x - 5 = 20

• multiply both sides by 5

• add 5 to both sides

• divide both sides by 5

• subtract both sides by 5

2 (n + 5) = -2 The first step in solving the following equation is ____________

• add five to both sides

• distribute 2 to all terms in the parenthesis

• add 2

7(x + 2) + 3 = 73 Step 1: Distribute
7x + 14 + 3 = 73 Step 2: Combine like terms
7x + 17 = 73 Step 3: Subtract 17
                    Step 4: Divide by 7     

• x = -8

• x = 8

• x = - 12.86

• x = 12.86

8v - 4(v + 8) = 8

• 2

• 10

• 4

• -4 

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

• 4

• 3

• 2

• 1
