What is the ordered pair for 2x - y = 8 and y = x - 3

The ordered pair for the given equations is (5,2)

Step-by-step explanation:

We are given two equations in this problem.

2x - y = 8

y = x - 3

Plug in y for the first equation so we can find x.

2x - (x - 3) = 8

Distribute the negative to (x - 3).

2x - x + 3 = 8

Subtract x from 2x.

x + 3 = 8

Subtract 3 from both sides of the equation.

x = 5

Now that we have the value of x, then we can plug in x for the second equation to find y.

y = 5 - 3

Subtract 3 from 5.

y = 2

So, the ordered pair for this equation is (5, 2)

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer
