Dahasolnce [82]

Answer:

The copy machine makes 32 copies per minute.

Step-by-step explanation:

If Y = 6x + 4 and 6x + 8 = 44, then Y=
Zolol [24]
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
