Question

Write the intercept cut off by the plane 2x + y − z = 5 on x-axis.

Answer 1

$$\begin{gathered} \text{For}\mathit{\text{x}}\text{- interecept, put}\mathit{\text{y}}\text{= 0 and}\mathit{\text{z}}\text{= 0 in the given equation. Then, we get} \\ 2x+0-0=5 \\ \Rightarrow 2x=5 \\ \Rightarrow x=\frac{5}{2} \end{gathered}$$
