Find the number of integral solution of $3x+1<10, x\in \mathrm{W}$.

Solve :$\frac{3x-1}{4}\le 8, x\in \mathrm{N}$

Solution of  $\frac{3x+1}{2}<5, x\in \mathrm{N}$ is $\left\{a, b\right\}$. Find the value of $a+b$.

Solve :$\frac{2x-5}{3}<3, x\in \mathrm{N}$

For solving an equation, we transpose all the terms containing the variable to the $LHS$ and all the constants to the $RHS$.

The solution to an equation cannot be negative.

Only one number line can be used for representing the solution of one inequation.

Solutions can be verified by substituting them in the equation.

Transposition is used for solving inequations also.
