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. In which step did I make the first mistake when solving this problem for x? x - 8 - 3x = 8x + 12 Step 4. 3.33 = x Step 2. - 8 = 6x + 12 Step 3. -20 = 6x Step 1. -2x - 8 = 8x + 12 6 6 step 1 step 2 step 3 step 4 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? step 4. step 2. step 3. step 1. -3x + 12 = x + 4 -3(x - 4) = x + 4 -4x = 16 x = -4 Step 1 Step 2 Step 3 Step 4 10. ⅓k - 3 = 5 11. 2(k - 1) = k + 5 Solve for k. Put your answers in the box. 9. -5k + 8 = -17 k = k = k = 12. -b = -5 13. 6b - 2b = -24 14. 2b + 5 = 2b + 4 + b + 2 Solve for b. b = b = b = 15. Is 3 t equivalent to yes or no -t 3 and -⅓ t ? 16. Solve -2 3 18 -18 8 -8 x = 12 The equivalent to "dividing by a fraction" is.... dividing by the reciprocal multiplying by the reciprocal guessing the answer multiplying by the decimal To solve the equation below I will first do.... ⅝ x = 10 divide both sides by 8 multiply both sides by 5 multiply both side by 8/5 divide both sides by 8/5 Drag the steps in to the correct order to solve the equation below: step 1: step 3: step 2: multiply both sides by three ? subtract three from both sides ? simplify and solve ? ⅓(x + 3) = 5 |
