Question

Find the solution of the following equations . Also , verify your answer .

$\mathrm{x}+7=11$

Answer 1

Given , the linear equation is $\mathrm{x}+7=11--------\left(1\right)$

Subtracting $-7$ on the both side of the given equation , we get

$\Rightarrow \mathrm{x}+7+\left(-7\right)=11+\left(-7\right)$

$\Rightarrow \mathrm{x}+7-7=11-7$

$\Rightarrow \mathrm{x}=4$

Hence , the required solution of the equation is $\mathrm{x}=4$ .

Check :- Putting $\mathrm{x}=4$ in the given equation $\left(1\right)$,

LHS $=4+7$

$=11$

Since, LHS $=$RHS $=$$11$

Hence, solution is verified.
