Question

Solve the following system of equations using the substitution method.

–6x + 2y = 8

y = 3x + 4

Answer 1

Infinite solutions or some courses say all real numbers

Explanation:

-6x + 2(3x + 4) = 8 substitute 3x + 4 for y

-6x + 6x + 8 = 8 Distribute the 2

8=8 The x's cancel out leaving a true statement. This means that there are infinite solutions.
