Answer:
x = 3 and y = -18
Step-by-step explanation:
y = -6x
y = -8x + 6
Both equations are equal to y. So,
y = -6x = -8x + 6
Solve for x first.
-6x = -8x + 6
Add 8x to both sides.
2x = 6
x = 3
Substitute x = 3 into y = -6x
y = -6 * 3
y = -18
Now, double check to see if this is correct.
y = -8x + 6
-18 = -8 * 3 + 6
-18 = -24 + 6
-18 = -18
x = 3 and y = -18 are correct.

To find a percentage increase of 15%, you can multiply the original value by 1.15.
To find a percentage increase of 20%, you can multiply the original value by 1.2.
117.7 * 1.15 = 135.355
So if she orders 15% extra tile, she will order around about 135.355 square feet.
117.2 * 1.2 = 141.24
And if she orders 20% extra tile, she will order around about 141.24 square feet.
Any number between those two values will be the amount of tile she might order.
785.63-(57+125)
=785.63-182
=603.63
603.63+57.25=$660.87
