Pre-Algebra Multi-Step Equations With Fractions and Decimals Solve p – 7 = 11. Lesson 7-3 p – 7 = Add 7 to each side.p – = Simplify. p = p = Multiply each side by, the reciprocal of p = Divide common factors. p = 24Simplify Additional Examples

Pre-Algebra Multi-Step Equations With Fractions and Decimals (continued) Lesson 7-3 Check: p – 7 = 11 (24) – 7 11Replace p with 24. Simplify. 18 – = – 7 11 Divide common factors Additional Examples

Pre-Algebra Multi-Step Equations With Fractions and Decimals Solve y + 3 =. Lesson 7-3 y + 3 = Multiply each side by 6, the LCM of 2 and 3. 6y + 3 = y + 18 – 18 = 4 – 18Subtract 18 from each side. 3y = –14Simplify. 3y + 18 = 4Simplify. Use the Distributive Property. 6 y = Divide each side by 3. 3y33y3 –14 3 = Simplify.y = – Additional Examples

Pre-Algebra Multi-Step Equations With Fractions and Decimals Lesson 7-3 Suppose your cell phone plan is $30 per month plus $.05 per minute. Your bill is $ Use the equation x = to find the number of minutes on your bill. There are 135 minutes on your bill x = x = 135Simplify. 30 – x = – 30Subtract 30 from each side. 0.05x = 6.75Simplify. Divide each side by 0.05.= x 0.05 Additional Examples
