Math Problem Statement

Solve the system of linear equations: y = x + 2 and 5x - 4y = -3.

Solution

The system of equations provided in the image is:

  1. y=x+2y = x + 2
  2. 5x4y=35x - 4y = -3

We will solve this system of linear equations using substitution.


Step 1: Substituting y=x+2y = x + 2 into the second equation:

5x4(x+2)=35x - 4(x + 2) = -3

Step 2: Simplify the equation:

5x4x8=35x - 4x - 8 = -3

x8=3x - 8 = -3

x=5x = 5


Step 3: Substitute x=5x = 5 back into y=x+2y = x + 2:

y=5+2y = 5 + 2

y=7y = 7


Final Solution:

x=5,y=7x = 5, \, y = 7
