Math Problem Statement

y=−x+5 y, equals, 2, x, minus, 1 y=2x−1

Solution

You have a system of linear equations:

  1. y=x+5y = -x + 5
  2. y=2x1y = 2x - 1

To find the solution for this system, set the expressions for yy equal to each other:

x+5=2x1-x + 5 = 2x - 1

Solve for xx:

  1. Add xx to both sides:

    5=3x15 = 3x - 1

  2. Add 1 to both sides:

    6=3x6 = 3x

  3. Divide both sides by 3:

    x=2x = 2

Now, substitute x=2x = 2 back into either of the original equations to find yy. Using the second equation:

y=2(2)1=41=3y = 2(2) - 1 = 4 - 1 = 3

Thus, the solution to the system of equations is x=2x = 2 and y=3y = 3. The point of intersection is (2,3)(2, 3).
