Question

How do you solve `[(4x),(5)]=[(15+x), (2y-1)]`?

Answer 1

I got that the equation is satisfied when:
`x=5`
`y=3`

Explanation:

The two matrices are equal when each corresponding elements are equal, i.e.:
`4x=15+x`
And
`5=2y-1`

Let us solve them:

`4x-x=15`
`3x=15`
`x=15/3=5`

And

`2y=5+1`
`y=6/2=3`
