Question

subtract the second equation from the first.6x + 5y = 16(6x + 2y = 10)

Answer 1

When the second equation is substracted from the first,

$\begin{gathered} (6x+5y)-(6x+2y)=16-10 \\ 3y=6 \\ y=2 \end{gathered}$

Thus, y=2 is the result when the second equation is substracted from the first.
