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

Answer:
Option D
Step-by-step 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.
