Solve the system of equations 3x5y 23 and 4x5y 7Solution3x

Solve the system of equations: 3x-5y = 23 and 4x-5y = -7

3x-5y = 23................(1)

4x -5y = -7 .................(2)

We will use the elimination method to solve.

We will subtract (1) from (2).

==> x = -30

Now we will substitute into (2) to find y.

==> 4x -5y = -7

==> 4*-30 - 5y = -7

==> -120 - 5y = -7

==>5y = -120 + 7 = -113

==> y= -113/5

Then the answer is the pair ( -30, -113/5)
