Question

How do you solve `\frac{1}{4} + \frac{1}{2} + x = - \frac{3}{4}`?

Answer 1

`x = -1 1/2`

Explanation:

Usually in an equation we would want to get rid of any fractions first.

However in this case, only a basic knowledge and understanding of fractions is required and it i not necessary get rid of the denominators.

`1/4 +1/2 + x = -3/4" "larr` add the fraction on the left

`color(white)(xxx)3/4 +x = -3/4`

`color(white)(xxxxxx)x = -3/4 -3/4`

`color(white)(xxxxxx)x = -6/4 = -1 1/2`
