1. Fill in the blank. Solve for x. 3 - x = 4 -x = 1 -1 x = -1 2. Fill in the blanks. Solve for x. • x = -5 4 x = x = -5 4 • 3. Fill in the blanks. Solve for x. -3x 3x + 5 = 6x - 16 21 = 3x 3 5 = 3x - 16 x = 3 4. Fill in the blanks. Solve for x. x - 8 - 3x = 8x + 12 +2x -20 = 10x - 8 = 8x - 2 - 8 = 10x + 12 10 +2x = x 10 -12 Solve for m. Type your answers in the boxes. 6. 7. 5. -3m = -9 5 - m = -4 m 3 = -2 m = m = m = 8. In which step is the first mistake? 2. 3. 4. 1. -3x + 12 = x + 4 -3(x - 4) = x + 4 -4x = 16 x = -4 Step 1 Step 2 Step 3 Step 4 10. k - 3 = 5 11. 2(k - 1) = k + 5 Solve for k. Put your answers in the box. 9. -5k + 8 = -17 3 k = k = k = 12. -b = -5 13. 6b - 2b = -24 14. 2b + 5 = b + 4 + b + 1 Solve for b. b = b = b = 15. Is 3 t equivalent to yes or no -t 3 and -3 t ? 16.
