X= y+7, 3x+2y=96
what is the solution of this sytem?

X=y+7
subsitute y+7 for x since they are equal

3(y+7)+2y=96
distribute
3y+21+2y=96
add like terms
5y+21=96
minus 21 from both sides
5y=75
divide both sides by 5
y=15

sub
x=y+7
x=15+7
x=22

solution where you have (x,y)
(22,15)

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
