Math Problem Statement

Solve the system of equations: 3x - 2y = 6 and y = x - 3.

Solution

The problem consists of a system of linear equations:

  1. 3x2y=63x - 2y = 6
  2. y=x3y = x - 3

Solution:

Step 1: Substitute y=x3y = x - 3 into the first equation

The first equation is 3x2y=63x - 2y = 6. Replace yy with x3x - 3: 3x2(x3)=63x - 2(x - 3) = 6

Step 2: Simplify

Distribute the 2-2 over (x3)(x - 3): 3x2x+6=63x - 2x + 6 = 6

Combine like terms: x+6=6x + 6 = 6

Step 3: Solve for xx

Subtract 6 from both sides: x=0x = 0

Step 4: Solve for yy

Use the second equation, y=x3y = x - 3, and substitute x=0x = 0: y=03y = 0 - 3

y=3y = -3

Final Answer:

The solution is: x=0,y=3x = 0, \, y = -3
