Question

How do you solve the system by graphing `3x-5y=8` and `x+2y=1`?

Answer 1

See below

Explanation:

`3x-5y=8`
`x+2y=1`

These can be represented as two straight lines on the `xy-`plane as below:

graph{(3x-5y-8)(x+2y-1)=0 [-10, 10, -5, 5]}

The solution of the system can be found at the point of intersection of the two lines. This point is `approx (1.91, -0.46)`

Hence:

`x approx 1.91`
`y approx -0.46`
