Solving using substitution and/or elimination method - 5x+6y=-8; x-4y=24

Hmm

we can solve for xin second equation

add 4y both sides

x=24+4y

sub 24+4y for x in other equation

-5 (24+4y) + 6y=-8

-120-20y+6y=-8

-120-14y=-8

add 120 both sides

-14y=112

divide bot sides by - 14

y=-8

sub back

x=24+4y

x=24+4 (-8)

x=24-32

x=-8

answer is

(x, y)

(-8,-8)
