Solve the system of linear equations below, using substitution method. 8x+9y=368x+9y=36
3x+4y=163x+4y=16

Given:

The system of equations is

To find:

The solution of the given system of equations using the substituting method.

Solution:

We have,

          ...(i)

           ...(ii)

From (ii), we get

         ...(iii)

Putting this value in (i), we get

Multiply both sides by 3.

Putting y=4 in (iii), we get

Therefore, the solution of given system of equations is (0,0).

0.02
