Dr Pooranmal and Ashfaq A Khan Solutions for Chapter: Linear Equations in One Variable, Exercise 5: CCE TEST PAPER

Which method is used for solving a linear equation?

If $\mathrm{x}=1, \mathrm{y}=2, \text{and} \mathrm{z}=3$ then $\left({\mathrm{x}}^2+{\mathrm{y}}^2+{\mathrm{z}}^2\right)=?$

Solve it, for $\mathrm{x}: 5\mathrm{x}-3\left(2\mathrm{x}-5\right)=2\left(\mathrm{x}+3\right)-7$

If $\frac{\mathrm{x}}{8}=1$ them

If $\frac{1}{4}\mathrm{x}+2=6$, then $\mathrm{x}=?$.

$5$ is added to a number gives $30$. So number is_____.

$\left({\mathrm{b}}^2-{\mathrm{a}}^2\right)-\left({\mathrm{a}}^2-{\mathrm{b}}^2\right)=$_____

The coefficient of $\mathrm{x}$ in $2\mathrm{xyz}$ is _____.
