Question

Find the solution of the system of equations.

Given the following equations:

  1. 7x−7y=77 7x - 7y = 77
  2. −4x−7y=−26 -4x - 7y = -26

Solution

The system of equations is:

  1. 7x - 7y = 7
  2. -4x - 7y = -26

First, simplify the equations:

  1. x - y = 1
  2. -4x - 7y = -26

Next, you can solve the first equation for x:

x = y + 1

Substitute x in the second equation:

-4(y + 1) - 7y = -26 -4y - 4 - 7y = -26 -11y - 4 = -26 -11y = -22 y = 2
