Solution
It looks like you've provided a system of three linear equations. Here they are written out:
x - y + 6z &= 2, \\ - y + 4z &= 0, \\ y + 5z &= 0. \end{aligned}$$ Let's solve this system step by step. ### Step 1: Solve the second equation for $$y$$. $$- y + 4z = 0 \implies y = 4z$$ ### Step 2: Substitute $$y = 4z$$ into the third equation. $$4z + 5z = 0 \implies 9z = 0 \implies z = 0$$ ### Step 3: Substitute $$z = 0$$ back into the expression for $$y$$. $$y = 4z = 4(0) = 0$$ ### Step 4: Substitute $$z = 0$$ and $$y = 0$$ into the first equation to solve for $$x$$. $$x - 0 + 6(0) = 2 \implies x = 2$$ ### Solution: $$\boxed{x = 2}, \quad \boxed{y = 0}, \quad \boxed{z = 0}$$ This is the unique solution to the system of equations.
