Answer:

7 w - 6 w = 10 d- 8 d

1 w = 2 d

then 10w - 7w = x- 10d

3w = x - 10d............(1 w = 2 d)

3(2d) = x - 10d

x = 10d +6d

x = 16d

<h2>Answer:</h2>

There are 2 ways to solve this system: by elimination or by graphing. I will solve it by elimination. First will solve for x.

$2x - 2y = 6\\3x + 2y = 9\\\\5x = 15\\\\x = 3\\$

Now we will solve for y using what we got for x.

$2(3) - 2y = 6\\\\6 - 2y = 6\\\\-2y = 0\\\\y = 0$

Solution:

A: $(0, 3)$
