Q. Solve the following system of linear equations: x1+x2+x3=22x1−x2+x3=92x1+3x2+4x3=4Determine the values of x1,x2,x3
.
Write Equations: Step 1: Write down the system of equations.Equations given:1. x1+x2+x3=22. 2x1−x2+x3=93. 2x1+3x2+4x3=4
Use Elimination: Step 2: Use elimination to simplify the equations.Eliminate x3 from equations 1 and 2:Add equation 1 and 2:x1+x2+x3+2x1−x2+x3=2+93x1+2x3=11
Substitute and Solve: Step 3: Substitute 3x1+2x3=11 into equation 3.Replace 3x1+2x3 in equation 3:3x1+2x3+3x2+4x3=46x2+6x3=−7 (This is incorrect, should be 3x2+2x3=−7)
