Using the "opposite operation" to "undo" and isolate the variable when solving an equation is more commonly called...

• Inverse operations

• math

• variable

• PEMDAS

What is the first step (after setting up your workspace) in solving this equation:
5x + 7 = 12

• Divide by 5

• Subtract 5

• Multiply by 7

• Subtract 7

Solve for w:

• 2

• 1.2

• 12

• -2

Translate:
Five more than a number

• x + 5

• 5x

• 5 - x

• 5 divided by x

Translate: 
Four times a number plus six IS 30.
