Question

First, solve the equation for y. Second, find the value of y for the given x-value.

3x - 2y = -7, when x = 3

Please help! And fast!

Answer 1

\[3x - 2y = -7\]
\[3 x+7 = 2 y\]
\[y = \dfrac{(3 x)+7}{2}\]
\[x = 3\]
\[y = \dfrac{3 (3)+7}{2}\]
\[y = \dfrac{9+7}{2}\]
\[y = \dfrac{16}{2}\]
\[y = 8\]
