Which of these shows results of using the first equation to substitute for y in the second equation then combine like terms y=2x 2x+3y=16 a.5y=16 b.4x=16 c.8x=16 d.5x=16 i think it is c

The correct option is (C).

Step-by-step explanation:  The given system of equations is

We are given to to choose the correct option that shows results of using the first equation to substitute for y in the second equation then combine like terms.

From equation (i), we have

Substituting the value of 'y' from here in equation (ii), we get

Therefore, the correct result is

Thus, option (C) is correct.
