Question

Which of these shows the result of using the first equation to substitute for Y in the second equation, then combining like terms?

Answer 1

Option D

Explanation:

Equations given in the question are y = 2x and 2x + 3y = 16

As per question we replace y = 2x in the second equation and combination the like terms.

2x + 3(2x) = 16

2x + 6x = 16

8x = 16

Option D will be the answer.
