<h3><u>The value of y is -2.5</u></h3><h3><u>The value of x is -2.</u></h3>
x - 8y = 18
-16x + 16y = -8
We can multiply each term in the first equation by 2 to better assist this elimination.
2x - 16y = 36
Now, we can use elimination.
Add equations together.
-14x = 28
Divide both sides by -14
x = -2
Now that we have a value for x, we can solve for y.
-2 - 8y = 18
Add 2 to both sides.
-8y = 20
Divide both sides by -8
y = -2.5
15x = -75 Divide both sides by 15.
Final answer: -5
hope that helps
101.48 i think
118 - (118 x .20) = 94.40 + (94.40 x .075) = 101.48
6% because...
7 x 6% = 7.42 (because 7 x 6 = 42)
Hope that this helps! c:
