Question #98353

Answer 1

See explanation

Explanation:

Note that `4xx6=24`

`4xxEquation(1) ->24x-20y=-14`
`6xxEquation(2)->ul(24x+12y=color(white)(..)168) larr" subtract"`
`" "0x-32y= -182`

`-32y=-182`

Multiply both sides by (-1)

`32y=182`

Divide both sides by 32

`32/32 y=182/32`

but `32/32=1`

`y=91/16`

Where you can, always use fraction. They are more precise than decimals. Using decimals introduces rounding errors.

Just substitute for `y` in `Equation(1) or 2` to determine `x`
