Question #321af

Answer 1

`x = 52, a = 39`

Explanation:

If you have equations which have fractions, you can get rid of the denominators by multiplying each term by the LCD

`x/8 -1/2 = 6 " " LCD = 8`

`(color(red)8 xx x)/8 -(color(red)8 xx 1)/2 = color(red)8 xx 6`

`(color(red)cancel8 xx x)/cancel8 -(color(red)cancel8^4 xx 1)/cancel2 = color(red)8 xx 6`

`x-4 = 48`

`x = 52`

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`15= a/3 -2" "xx3`

`color(blue)3xx15= (color(blue)(cancel3xx)a)/cancel3 - color(blue)(3xx)(-2)`

`45 = a +6`

`39 = a`
