Akilah Short Valerie McGraw Algebra 2/18/20 2.03 Assignment Problem set: Combining Like Terms 1.) 16x-4x=-48 Combine like terms: 12x= -48 Divide by 12: 12 12 = -4 /12 X= -4 2.) 7m – 5 - 13m = 25 Combine like terms: -6m – 5 = 25 Add 5; -6m – 5 + 5 = 25 + 5 -6m = 30 -6m divide -6 = 30 divide -6
M = 5 3. 12.25 = 0.5q + 3.75 Subtract 3.75: 0.5q + 3.75 – 3.75 = 12.25 – 3.75 0.5q = 8.5 Divide 0.5: 0.5q divide 0.5 = 8.5 divide 0.5 Q = 17 4.) 2(2x - 4) + x = 7 Distributive property: (2 x 2x) + (2 x -4) + x = 7 4 + x – 8 = 7 Combine like terms: 5x – 8 = 7 Add 8: 5x – 8 + 8 = 7 + 8 5x = 15
Divide by 5: 5x/5 = 15/5 X = 3 5.) 8 = 3(3x + 8) – x Distributive property: (3 x 3x) + (3 x 8) – x = 8 9x + 24 – x = 8 9x – x + 24 = 8 Subtract 24: 8 + 24 -24 = 8 – 24
