The goal of solving two-step equations is to:

• francine
• Find the coefficient 
• Find the value of the variable

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 in solving this equation:
5x + 7 = 12

• Divide by 5
• Subtract 5
• Add 7
• Subtract 7

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 -3 + 2x = -1 

• x = 3
• x = 2
• x = 1
• x = -2

Solve  9 - 5t  = 24

• t = -3
• t = 3
• t = -6.6
• t = 12

• t = 20
• t = -20
• t = -40
• t = 40

Solve   2y - 4 = -10

• y = -7
• y = 3
• y = -3
• y = 7
