GRE Sample Test 2 Quantitative Reasoning 2

Solve for x in the top equation,

x

6

+2 =

6

2

,
by reducing the right side:

x

6

+2 = 3.
Subtract 2 from both sides, and multiply both sides by 6 to find that x = 6. Solve for y in the second equation,

y

3

+2 =

9

3

, by reducing the right side:

y

3

+2 = 3.
Subtract 2 from both sides, and multiply both sides by 3 to find that y = 3. If x = 6 and y = 3, Quantity A becomes

5

3

, and Quantity B becomes

2

6

=

1
