Question

Use the substitution method to solve the system of equations. Choose the correct ordered pair. 2x + y= 8 and y= -x + 5

Answer 1

The ordered pair is (3, 2).

Explanation:

y = -x + 5

2x + y = 8

Substitute y = -x + 5 in the second equation:

2x + (-x + 5) = 8

x + 5 = 8

x = 3.

Now substitute x = 3 into the first equation;

y = -3 + 5

y = 2.
