Teaching CTET (Paper 1 & Paper 2) Mock Test Series 2025 Quantitative Aptitude Algebra Linear equation in 3 variable
Find the values of x, y and z, so as to satisfy the equations given below: 5x – 3y + 7z = 22; 3x – 5y – 2z = – 46; 2x – 2y + 5z = 24
1
x = – 5, y = 3, z = – 8
2
x = 5, y = – 8, z = 3
3
x = – 5, y = 3, z = 8
4
x = – 5, y = – 3, z = 8
