What does it mean to "solve for" a variable?

• To isolate the variable

• Get that variable by itself

• To find what value that variable represents

What step would you take to solve this equation?

• Multiply both sides of the equation by 2
• Divide both sides of the equation by 2
• Add 2 to both sides of the equation
• Subtract 2 from both sides of the equation

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.

• Subtract 7 from both sides

• Add 12 to both sides
