Question

Combine like terms.
7/8x - 1/2x



A. 1/8x


B. 3/8


C. 3/8x


D. x

Answer 1

First, find a common denominator for both fractions, in this case we can use 8.
So we leave 7/8 x unchanged, by multiply -1/2 x by 4/4
\[\huge \frac{ 7 }{ 8 } x - \frac{ 1 }{ 2 }x \]
\[\Huge \frac{ 7 }{ 8 } x - \frac{ 4 }{ 8 }x \]
Can you simplify from here?
