Determine if x = 4 is a solution to the equation.
12 + 5x - 8 = 12x - 10

• True
• False

Determine if x = 6 is a solution to the equation.
2(3x - 4) = 3x + 1

• True
• False

4 + 2 = 5 + 1

• True

• False

Are the equations true?

49 + 23 = 47 + 25

• True

• False

I am trying to solve

10 - x = 3

I can add 10 and 3 to find the unknown number.

• True

• False

12+5w-4w=15

• w=1
• w=3
• w=5
• w=4

10(h+1)-4=76

• h=10
• h=4
• h=7
• h=76

Combine like terms and solve: 
4(y +4) = 46 – 2y

• x = 5 
• x = 6
• x = 7
• x = 8

Simplify each equation. Tell whether the equation has one, no, or infinite solutions.
3x - 8 = 3(x - 4) + 1

• one
• no solutions
• infinite solutions

Which property justifies the second step?
          4x + 8 = 0
               - 8    - 8

• Subtraction Property of Equality
• Addition Property of Equality
• Identity Property of Addition
• Commutative Property of Addition
