Solving Basic Equations (Topics)

What is the difference between an expression and an equation?

• Equations have = sign and expressions do not

• Expressions have = signs and equations do not

• One have variables and numbers

• Equations have < and > signs

Solve for x:

4(1 - x) + 3x = -2(x + 1)

• x = -6

• x = 6

• x = 3

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.
