You would divide 456 miles by the number of gallons used to get the answer of 38 miles per gallon.
<h3>The solution is (x, y) = (3, -24)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
-3x - y = 15 -------- eqn 1
y = -8x ------ eqn 2
We have to find solution of (x, y)
We can solve by substitution method
<em><u>Substitute eqn 2 in eqn 1</u></em>
-3x - (-8x) = 15
-3x + 8x = 15
5x = 15
Divide both sides by 5
<h3>x = 3</h3>
Substitute x = 3 in eqn 2
y = -8(3)
<h3>y = -24</h3>
Thus solution is (x, y) = (3, -24)
Set the bottom equal to 0
x - 8 = 0
x = 8
The value for x is already given; x = -2
Substitute -2 in for x in the second equation.
y = 2/3(-2) + 3
y = -4/3 + 3
y = 5/3
The final answer is (-2, 5/3).
2/3 ÷ 4/1
2/3 • 1/4
2/12
1/6
