Math Problem Statement

2x+3y=4 y+3x=6

Solution

To solve the system of linear equations:

  1. 2x+3y=42x + 3y = 4
  2. y+3x=6y + 3x = 6

We'll use substitution or elimination. Let's use substitution in this case.

Step 1: Solve the second equation for yy

From y+3x=6y + 3x = 6, isolate yy: y=63xy = 6 - 3x

Step 2: Substitute this expression for yy into the first equation

Substitute y=63xy = 6 - 3x into 2x+3y=42x + 3y = 4: 2x+3(63x)=42x + 3(6 - 3x) = 4 Now, simplify: 2x+189x=42x + 18 - 9x = 4 7x+18=4-7x + 18 = 4 7x=418-7x = 4 - 18 7x=14-7x = -14 x=2x = 2

Step 3: Substitute x=2x = 2 back into the expression for yy

Now that we know x=2x = 2, substitute this into y=63xy = 6 - 3x: y=63(2)y = 6 - 3(2) y=66y = 6 - 6 y=0y = 0

Final Solution

The solution to the system is: x=2,y=0x = 2, \quad y = 0
