Solve the system of equations by multiplying first. Enter the solution as an ordered pair. x + 3y = -13

4x + 4y = -12

The solution is

Given:

The system of equations is:

To find:

The solution for the given system of equations.

Solution:

We have,

           ..(i)

         ...(ii)

Multiply equation (i) by 4, to make common coefficient of x.

           ..(iii)

Subtract (ii) from (iii).

Putting in (i), we get

Therefore, the solution of the given system of equations is .
