Solution

1. Break Down the Problem

We need to solve the following system of equations:

  1. x3y=5 x - 3y = 5
  2. 2x+y=10 2x + y = 10

2. Relevant Concepts

To solve a system of linear equations, we can use either the substitution method, the elimination method, or graphical methods. Here, I will use the elimination method.

3. Analysis and Detail

  1. Rearranging the equations:

    • From Equation 1: x=3y+5 x = 3y + 5
    • Substitute x x from Equation 1 into Equation 2.
  2. Substituting: 2(3y+5)+y=10 2(3y + 5) + y = 10 Simplifying this: 6y+10+y=10 6y + 10 + y = 10 7y+10=10 7y + 10 = 10 7y=1010 7y = 10 - 10 7y=0 7y = 0 y=0 y = 0

  3. Finding x x : Substitute y=0 y = 0 back into Equation 1: x3(0)=5 x - 3(0) = 5 x=5 x = 5

4. Verify and Summarize

The solution to the system of equations is (x,y)=(5,0) (x, y) = (5, 0) .

Final Answer

The solution to the system of equations is (5,0) (5, 0) .
