solve using elimination.
8x + 10y = 14
8x + 9y = 19
(□, □)

Question

Accepted Answer

# Explanation:
## Step1: Subtract the two equations
Subtract the second equation $8x + 9y = 19$ from the first equation $8x + 10y = 14$ to eliminate $x$.
$$
\begin{align*}
(8x + 10y)-(8x + 9y)&=14 - 19\
8x + 10y - 8x - 9y&=-5\
y&=-5
\end{align*}
$$
## Step2: Substitute y into an equation
Substitute $y = - 5$ into the first equation $8x+10y = 14$.
$$
\begin{align*}
8x+10\times(-5)&=14\
8x-50&=14\
8x&=14 + 50\
8x&=64\
x&=8
\end{align*}
$$
