• c = -15

Which equation has x =2 as a solution?

• 3 + x = 10
• 11 + x = 13
• 4x = 32
• 5x =25

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• Combine Like Terms.

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Solve: 4x + 3 = -5

• 1/2
• -1/2
• -2
• 2
