2x+y+z=2 4x-2y-3z=-2 8x+3y+2z=5 in the beginning write down the coefficients [ 2 a million a million 2 ] -->R1 [ 4 -2 -3 -2 ] -->R2 [ 8 3 2 5 ] -->R3 R1 [ 2 a million a million 2 ] -->R1 2R1 - R2 [ 0 4 5 6 ] -->R2 4R1 - R3 [ 0 a million 2 3 ] -->R3 R1 [ 2 a million a million 2 ] R2 [ 0 4 5 6 ] 4R3 - R2 [ 0 0 3 6 ] Now 3z = 6 z = 6/3 z = 2 4y + 5z = 6 4y + 5(2) = 6 4y + 10 = 6 4y = 6 - 10 4y = -4 y = -a million 2x + y + z = 2 2x + (-a million) + 2 = 2 2x = 2 - 2 + a million 2x = a million x = a million/2 This called augmented matrix. you additionally can try this on a photographs calculator and is a lot much less confusing to realize this.

Subtract 4x from both sides
2y = -6 - 4x
Divide both sides by 2
y = -(3+2x)
