4-6 Solving Equations with Fractions What You’ll Learn ► To solve one – step equations ► To solve two – equations

Skills Check ► Solve each equations  3x + 7 = 37  11j – 84 = 92  31 = 7w - 11

Solving by Adding or Subtracting ► Solve n – ½ = 4 ¾  n – ½ = 4 ¾  n – ½ + ½ = 4 ¾ + ½  n = 4 ¾ + 2/4  n = 4 5/4 or 5 ¼

Solving by Adding or Subtracting ► Solve x – 7/8 = 1 ½ ► Solve h - 2/5 = 9/10

Solving by Multiplying or Dividing ► Solve s/ 4 = 44  S / 4 = 44  S / 4 *4/1 = 44 * 4  s = 176

Solving by Multiplying or Dividing ► Solve 1/3s = 5 ► Solve t/8 = 3

Solving Two – Step Equations ► Solve 2/3 n – 6 = 22  2/3 n – 6 = 22  2/3 n – =  3/2 * 2/3 n = 28 * 3/2  n = 42

Solving Two – Step Equations ► Solve ¼ x + 3 = 11 ► Solve 3/5 g – 5 = 7
