Question

Solve the system of equations. ​

Answer 1

x = -1

y = -2

Explanation:

The two equations are:

`$ -4x + 3y = -2 \hspace{25mm} ........(1) $`

`$ y = x - 1 \hspace{25mm} .......(2) $`

Substituting (2) in (1) we get:

`$ -4x + 3(x - 1) = -2 $`

`$ \implies -4x + 3x - 3 = -2 $`

`$ \implies -x = 1 $`

∴ x = -1

Substituting the value of x in (2), we get

y = -1-1 = -2.

∴ y = -2
