Question

2x + 3y = 8
3x + y = 2
Solve the system of equations using elimination.

Answer 1

2, -4

Explanation:

substitute

`\begin{bmatrix}2x+3y=-8\\ 3x+y=2\end{bmatrix}`

simplify

`\begin{bmatrix}3\cdot (-8-3y)/(2)+y=2\end{bmatrix}`
`\begin{bmatrix}(-24-7y)/(2)=2\end{bmatrix}\\`

isolate

`x=(-8-3\left(-4\right))/(2)`

and then u get x = 2

and y = 4
