x खातीर x+y-3z+6=2c सोडोवचो.

$$x=-y+3z-6+2c$$

दुस-या आनी तिस-या समिकरणांत x खातीर -y+3z-6+2c बदलपी घेवचो.

$$3\left(-y+3z-6+2c\right)-y+z-t=2a -\left(-y+3z-6+2c\right)+3y-z+t=2b$$

अनुक्रमान y आनी z खातीर हीं समिकरणां सोडोवचीं.

$$y=\frac{5}{2}z-\frac{9}{2}+\frac{3}{2}c-\frac{1}{4}t-\frac{1}{2}a z=y-\frac{1}{2}b+\frac{3}{2}-\frac{1}{2}c+\frac{1}{4}t$$
