Question

Pick out one value from the two values given in the bracket to make a true statement.

$3\mathrm{x}=30;\left(10,11\right)$

Answer 1

Given equation is $3\mathrm{x}=30$.

Step $1$ : Substituting $\mathrm{x}=10$ in the above equation.

We get, LHS $=3\times 10=30$ and RHS $=30$

Since LHS$=$RHS

Therefore, the above equation is true for $\mathrm{x}=10$.

Step $2$ : Substituting $\mathrm{x}=11$ in the above equation.

We get, LHS $=3\times 11=33$ and RHS $=10$

Since LHS$\ne$RHS

Therefore, the above equation is not true for $\mathrm{x}=11$.

Hence, the answer is $\mathrm{x}=10$.
