To solve an equation using substitution - the equations are y=6x-11

-2x-3y = - 7

So we see we got y=6x-11

sub 6x-11 for y int other eqution

-2x-3 (6x-11) = - 7

expand/distribute

-2x-18x+33=-7

-20x+33=-7

minus 33 both sides

-20x=-40

divide both sides by - 20

x=2

sub back

y=6x-11

y=6 (2) - 11

y=12-11

y=1

x=2

y=1

(x, y)

(2,1)
