Intro to Math U6L1 CYK

How many steps would it take to solve the following equation?

x + 2 = 5

• 0 (This equation can't be solved!)

• one

• two

When solving equations, the first thing we ask ourselves is “What is the ____________?” ("What am I trying to solve for?")

• variable

• coefficient

• absolute value

What is the opposite operation needed to solve the following equation?

• Divide both sides by 3

• Subtract 3 from both sides

• Multiply both sides by 3

Solve: x - 4 = 9

• x = 13

• x = 5

• x = 9

Solve: 4a - 9 = 27

• a = 36

• a = 9

• a = 4.5
