Question

How do you solve `\frac { 1} { 4} a - \frac { 1} { 4} = - 2`?

Answer 1

`a=-7`

Explanation:

Note that `1/4a=a/4`

`rArra/4-1/4=-2`

To eliminate the fractions, multiply all terms on both sides of the equation by 4

`(cancel(4)^1xxa/cancel(4)^1)-(cancel(4)^1xx1/cancel(4)^1)=(4xx-2)`

`rArra-1=-8`

add 1 to both sides.

`acancel(-1)cancel(+1)=-8+1`

`rArra=-7" is the solution"`
