- y = -18
- y = -72 (You need to multiply by the reciprocal.)
- y = -32/9 (You need to multiply by the reciprocal.)
- y = -27/2 (You should subtract 2 from both sides first.)
A: y = -18

Show the steps you would use to solve the equation.

Q: Solve the equation. Check your solution.

\[\frac{1}{3}\]f - 4 = 1
- f = -9 (incorrect)
- f = -15 (incorrect)
- f = 15 (correct)
- f = 9 (incorrect)
A: f = 15

Q: Solve the equation. Check your solution.

 9 – \[\frac{x}{3}\] = 17
- x = -11 (incorrect)
- x = 80 (incorrect)
- x = -24 (correct)
- x = 24 (I recommend changing subtraction to adding the opposite so you don't lose negative signs.)
A: x = -24

Q: Solve the equation. Check your solution.

\[\frac{1}{5}\]f - 3 = 1
- f = 20 (correct)
- f = -10 (incorrect)
- f = -20 (incorrect)
- f = 10 (incorrect)
A: f = 20

Q: Solve. Check your solution.

0.4x + 3.9 = 5.78
- x = 4.7
- x = 24.2 (You need to subtract 3.9 or add -3.9 to both sides first.)
- x = 0.752 (Remember you undo multiplication by dividing.)
- x = -6.5 (Incorrect)
A: x = 4.7

Q: Solve the equation. Check your solution.

\[\frac{x}{9}\] + 6 = 11
- x = 14 (incorrect)
- x = 155 (incorrect)
- x = 45 (correct)
- x = 153 (incorrect)
A: x = 45

Q: Solve. Check your solution.

- y = 18 (You should add 10 to both sides first.)
- y = 16 (Get rid of the subtraction before multiplying.)
- y = -6 (Correct!)
- y = -25/6 (Multiply by the reciprocal.)
A: y = -6

Q: Solve the equation. Check your solution.

\[\frac{1}{2}\] g - 5 = 1
- g = -8 (incorrect)
- g = -12 (incorrect)
- g = 12 (correct)
- g = 8 (incorrect)
A: g = 12

Q: Solve the equation. Check your solution.

 -4 – \[\frac{x}{4}\]  = 12
- x = 32 (You should add 4 to both sides first.)
- x = -32 (You should add 4 to both sides first.)
- x = -64 (Correct)
- x = 64 (You may have lost the negative in front of the x/4)
A: x = -64

Q: Solve. Check your solution.

[Image]
- y = 1 (You should multiply by the reciprocal of 3/5)
- y = 25/9
- y = -5/9 (You should add 1 to both sides first.)
- y = -10/9 (You should add 1 to both sides first.)
A: y = 25/9

Q: Solve the equation. Check your solution.

\[\frac{1}{3}\]a - \[\frac{1}{3}\] = -3
- a = 8 (incorrect)
- a = -10 (incorrect)
- a = -8 (correct)
- a = 10 (incorrect)
A: a = -8

Q: Solve. Check your solution.

- w = 1.25 (You need to add 3/4 to both sides first.)
- w = 2
- w = -2 (Careful about negative signs.)
- w = 3.75 (Incorrect.)
A: w = 2
