Bluebook SAT Test Linear Equations in One Variable 16

Question 1

If 6x − 10 = 2(x + 3), what is the value of x?

Accepted Answer

5

Answer

6x − 10 = 2x + 6 → 4x = 16 → x = 4.

Question 2

Solve for x: 2x/3 + 4 = x/2 + 7

Accepted Answer

18

Answer

Multiply by 6: 4x + 24 = 3x + 42 → x = 18.

Question 3

A tank is filled by Pipe A at 20 gallons per minute and drained by Pipe B at 8 gallons per minute. How many minutes does it take to accumulate 60 gallons?

Accepted Answer

5

Answer

(20 − 8)t = 60 → 12t = 60 → t = 5.

Question 4

If 5(x − 3) = 3(x + 1) + 2, what is x?

Accepted Answer

10

Answer

5x − 15 = 3x + 3 + 2 → 2x = 20 → x = 10.

Question 5

In the equation 3x − d = x + 11, if d = 1 what is x?

Accepted Answer

6

Answer

3x − 1 = x + 11 → 2x = 12 → x = 6.
