1. 16x − 4x = -48 16x-4x=12x 12x= -48 X= 4 2. 7m − 5 − 13m = 25 7m – 13m = -6m -6 m -5 = 25 3. . 12.25 = 0.5q + 3.75 4. 2(2x−4)+x=7 (2·2x−2·4)+x=7 (4x−8)+x=7 4x−8+x=7 4x+x−8=7 5x−8=7 (5x−8)+8=7+8 5x−8+8=15 5x 5 =15 x= 3·5/5 x=3 5. 8 = 3(3x + 8) – x 3x +8 = 11 8=3(11)-x 11x3 =33 33- 8= 25 25= x 6. 2 7. 13.75 = 0.25b + 0.50 Reorder the terms: 13.75 = 0.50 + 0.25b Solving 13.75 = 0.50 + 0.25b Move all terms containing b to the left, all other terms to the right.
Add '-0.25b' to each side of the equation. 13.75 + -0.25b = 0.50 + 0.25b + -0.25b Combine like terms: 0.25b + -0.25b = 0.00 13.75 + -0.25b = 0.50 + 0.00
