Answer:
Step-by-step explanation:
-3x + 3y = 6.......(1)
y= 4x + 5............(2)
Putting (2) in (1)
-3x + 3(4x + 5) = 6
-3x + 12x + 15 = 6
9x = 6 -15
9x = -9
x = -9/9
x = -1
Putting x in (2)
y= 4x + 5
y = 4(-1) + 5
y = -4 + 5
y = 1
I=5+10h
i=75
75=5+10h
-5 both sides
70=10h
÷10 both sides
h=7
With the information given, we can conclude Anthony worked on Steve's bike for 7 hours.
We know this, if we set 75 equal to the formula given and solve for h.
