-7x-4y=1(-3-5)

-7x-4y=1(-3-5) solve for x. solve right side

-7x-4y=-8      add 4y to both sides

-7x=4y-8    divide both sides by -7(to make x positive)

x=(4y/-7)+1.42   answer

or

-7x-4y=1(-3-5) solve for y. solve right side

-7x-4y=-8 add 7x to both sides

-4y=7x-8   divide both sides by -4( to make y positive)

y=-1.75+2   answer
