Question

Solve the equation below :

7/8 = q + 1/2

A : q = 3/8


B : q = 1 3/8


C : q = 7/16


D q = 1 3/4

Answer 1

q = -3/8

Explanation:

Clearing out the fractions first simplifies this problem. The LCD here is 8, so we multiply all three terms of 7/8 = q + 1/2 by 8 and simplify the result:

7 + 8q = 4.

Combining the constants, we get: 8q = 4 - 7, or 8q = -3.

Finally, solve for q:

q = -3/8
