Question

Use the substitution method to solve the system of equations. Choose th correct ordered pair. y = 8x - 4 x = 4 A. (2. 12) OB. (4, 28) C. (4, 4) D. (2.4)

Answer 1

9514 1404 393

Answer:

B. (4, 28)

Explanation:

Substitute the value of x into the first equation. This gives you the value of y.

• y = 8x -4
• x = 4

After substitution, we have ...

y = 8(4) -4

y = 28

Then the point is (x, y) = (4, 28).
