Answer:18,000
Step-by-step explanation:
There is a yard = inches converter on google that can help you.
For this case we have the following system of equations:
2x-4y = -6
3x + 2y = -1
Step 1:
We rewrite equation 2:
2x-4y = -6
6x + 4y = -2
Step 2:
We add both equations:
8x = -8
Step 3:
We clear x:
x = -8/8
x = -1
Step 4:
We use any equation and we clear y:
3x + 2y = -1
2y = -1-3x
y = -1 / 2 - (3/2) * x
y = -1 / 2 - (3/2) * (- 1)
y = -1 / 2 + (3/2)
y = 2/2
y = 1
Answer:
x = -1
y = 1
