Systems of equations have

• an equation and at least one variable..

• two or more equations and at least one variable

• two or more equations and variables.

• two or more equations and the same variables.

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 for y.
8x + 4y= 16

• y = -8x + 16
• y = 2x -4
• y = -2x + 4
• y = -8x + 12
