AlgebraExamples

• 3/8 1/4x 1/2x 3/4
• 8(3/8 1/4x) 8(1/2x 3/4) (Multiply
  both sides by 8)
• 8(3/8) 8(1/4x) 8(1/2x) 8(3/4)
• 3 2x 4x 6
• 3 -2x 2x 4x 2x 6 ( add 2x to
  both sides)
• 3 6x 6
• 3 6 6x - 6 6 ( add 6
  to both sides)
• 9 6x (
  divide both sides by 6)
• 3/2 x

Examples

• Solve
• 5n 4 7(n 1) 2n (Distribute)
• 5n 4 7n 7 2 ( add like terms on same
  side) 5n 4 5n 7 ( get
  like terms on the same side)
• 5n 5n 4 5n 5n 7
• 4 7
• No solution!

Examples

• Solve
• 7 2(x 1) 2x 9 (distribute)
• 7 2x 2 2x 9 (add like terms on
  the same side)
• 2x 9 2x 9 ( reflexive
  property)
• Infinitely many
  solutions!
