Standard form for y=3×-2

3x-y=2

Step-by-step explanation:

y=3x-2

(y-3x)=-2

-3x+y=-2

change the signs on both sides

3x-y=2

=3x-y=2

To answer this question, you will represent the amount of yards rushed by each running back.

x - Running back #1
9x - Running back #2

The combined yards was 1550, so put these together in an addition equation with a total of 1550.  Solve for x.

x + 9x = 1550
10x = 1550
x = 155

Running back #1 rushed 155 yards, and running back #2 rushed for 1395 yards.
