Solving Equations SEA Review

The goal of solving two-step equations is to:

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

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 2x - 3 = 1 

• 3
• 2
• 1
• -2

Solve the equation
3x = 27. 

• x = 24
• x = 81
• x = 9

x - 62 = 123
How should you show your work to isolate the variable and solve the equation?

• Add 62 to each side. 
• Subtract 62 from each side.
• Multiply each side by 62.
• Add 123 to each side.

Word that means opposite.  We use this word when talking about "un-doing" an equation to solve it. 

• Reciprocal
• Operation
• Inverse
• quadrant

r + 12 = 25

• 37
• 13
• 300
• Answer not Given

What is your first step when you solve  x + 5 = 12

• Add 5 to 5 and add 5 to 5 to 12
• Subtract 5 from 5 and subtract 5 from 12
• Subtract 12 from 12 and subtract 12 from 5
• Add 12 to 12 and add 12 to 5
