You can use the substitution method. Using the first equation in terms of y,
y = 5 - x
Substitute this to the second equation to get the value of x.
x - 2(5 - x) = 2
x - 10 + 2x = 2
3x = 2 + 10
3x = 12
x = 4
For y, just substitute the value of x that we have used in the first equation.
y = 5 - 4 = 1
Therefore, in coordinate form, that is (4,1)
Answer:I dont know if this is a yes or no question but if it is the answer would be yes because they could spend half of the 87 hours washing cars and make $478.50 and spend the other half of the time on icecream making $217.50

Answer:
(0,7/6)
Step-by-step explanation:
Angles on a straight line add up to 180°
180- 130 = 50
180- 96 = 84
angles in a triangle add up to 180°
50 + 84 = 134
180- 134= 46
x = 46°
The answer for all of them are 28v4 = 7, 12v5= 60, and 20vs2= 10
