Shannon graphed the system of equations.
7x – 4y= –8
y = 3/4x – 3
what is the closest approximate solution to the system of equations?
a (–5, –7.2)
b (–5, –6.8)
c (–5, –6.2)
d (–5, –5.9)

Hello,

7x-4y=-8 (1)
y=3/4x-3==>3x-4y=12 (2)
(1)-(2)==>4x=-20 ==>x=-5

if x=-5 then (1)==>4y=-35+8==>y=-6.75

Answer B

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
