If Y = 6x + 4 and 6x + 8 = 44, then Y=

Assuming second equation is 6x+8y=44

so first divide 2nd eqation by 2 to make it eqaier

3x+4y=22

sub 6x+4 for y

3x+4 (6x+4) = 22

3x+24x+16=22

minus 16 both sides

27x=6

divide both sides by 27

x=2/9

sub back

y=6x+4

y=6 (2/9) + 4

y=12/9+4 (4=36/4)

y=48/9

Y=40 and x = 6

Good luck
