Question

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

$x+7=15$

Answer 1

Given , the linear equation is $x+7=15\_\_\_\_\_\_\_\_\_\_\_\_\left(1\right)$

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

$\Rightarrow x+7+\left(-7\right)=15+\left(-7\right)$

$\Rightarrow x+7-7=15-7$

$\Rightarrow x=8$

So, the required solution of the equation is $x=8$ .

Check :- Putting $x=8$ in the given equation $\left(1\right)$,

LHS $=8+7$

$=15$

Since, LHS $=$RHS $=$$15$

Hence, solution is verified.
