CCSS 8.EE.7 Prerequisite Skills for Engage NY Module 4 Step 1: Combine Like Terms. Step 1: Combine Like Terms. Step 2: Isolate the Variable. Step 2: Isolate the Variable. -15 = 10x – 40x 8x + 14 = 38 -15 = -30x - 14 - 14 -30 -30 8x = 24 ½ 3 Therefore x = ? Therefore x = ?

15-1.25p=10 2w -14 = 28 ½b -2 = 6 -1.25p = -5 2w = 42 ½b = 8 16 4 21 p = ? b = ? w = ?

-14 = 9w + 8.5 5.5n = 44 n = ? w = ?

Simplified Equation: (10½x ) + (2) = 65 2x + (3¼x + 1) + 2x + (3¼x + 1) = 65 Simplified Equation: (10½x ) + (2) = 65 c + f + d = 12.50 All items are made in comparison to the price of the fries. We can substitute in this situation. We know that: 1c = 3f and 1d = 1f Rewrite equation  3f + f + f = 12.50
