8M: 2-5 QC (solving for y)

1a. What would you do first in the equation below to solve for y? subtract 2 from both sides add 2 to both sides 1b. If the equation above is solved for y, which equation below would be correct? Drag the correct equation to the "correct" spot and the other equation to the "wrong" spot. CORRECT: y = 3x - 5 ? 2y = 6x-10 multiply 2 to both sides divide both sides by 2 WRONG: y=6x-12 ? 2a. What would you do first in the equation below to solve for y? subtract 4 from both sides add 4 to both sides 2b. If the equation above is solved for y, which equation below would be correct? Drag the correct equation to the "correct" spot and the other equation to the "wrong" spot. CORRECT: y = 6x + 4 ? y - 4 = 6x multiply -4 to both sides divide both sides by -4 WRONG: y = 6x - 4 ? add 4 to both sides subtract 4 from both sides 3a. What would you do first in the equation below to solve for y? 3b. If the equation above is solved for y, which equation below would be correct? Drag the correct equation to the "correct" spot and the other equation to the "wrong" spot. CORRECT: y = 8x ? y = 2x4 multiply 4 to both sides divide both sides by 4 WRONG: y = 2x + 4 ? 4a. What would you do first in the equation below to solve for y? subtract 11 from both sides add 11 to both sides 4b. If the equation above is solved for y, which equation below would be correct? Drag the correct equation to the "correct" spot and the other equation to the "wrong" spot. CORRECT: y = -4x - 11 ? y + 11 = -4x multiply 11 to both sides divide both sides by 11 WRONG: y = -4x + 11 ? 5a. What would you do first in the equation below to solve for y? subtract -3 from both sides add -3 to both sides 5b. If the equation above is solved for y, which equation below would be correct? Drag the correct equation to the "correct" spot and the other equation to the "wrong" spot. CORRECT: y = -3x + 5 ? -3y = 9x-15 multiply -3 to both sides divide both sides by -3 WRONG: y = 3x - 5 ? |
