Question

How do you solve `2x+5y=11` and `4x+3y=1` using substitution?

Answer 1

`y=3,x=-2`

Explanation:

We have `2x=11-5y`

Multiplying both sides by `2`,we get `4x=22-10y`

substituting this value in `2`nd equation,we have,

`22-10y=1-3y`

Or,`21=7y`

Thus,we get, `y=3` and substituting this value in first equation we get `x` as `-2`
