You have to divide 450 by 18 because that's how much money he makes per every lawn he mows, $20 is the amount he's paid minus $2 because he spends that much on gas per lawn mowed. Therefor you get 25
I thinks it’s 97.2222 repeating
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
Answer:
Step-by-step explanation:
I know you need to use elimination...
But if you Graph the lines the intersection is the answer.
The Answer is (-4,-8)
