Give the steps you will use to separate the variable and then solve the equation.
$5 m+7=17$
AnswerWe have, $5 m+7=17$
On subtracting 7 from both sides, we get
$
5 m+7-7 =17-7$
$\Rightarrow 5 m =10
$
Now, on dividing both sides by 5 , we get
$
\frac{5 m}{5}=\frac{10}{5} \Rightarrow m=2
$
Hence, $m=2$ is the solution of the given equation.

Give the steps you will use to separate the variable and then solve the equation.
$3 n-2=46$
AnswerWe have, $3 n-2=46$
On adding 2 to both sides, we get
$
\begin{array}{rlrl}
3 n-2+2 & =46+2 \\
\Rightarrow 3 n=48
\end{array}
$
Now, on dividing both sides by 3 , we get
$
\frac{3 n}{3}=\frac{48}{3} \Rightarrow n=16
$
Hence, $n=16$ is the solution of the given equation.

Give first the step you will use to separate the variable and then solve the equation.
$\frac{b}{2}=6$
AnswerWe have, $\frac{b}{2}=6$
On multiplying both sides by 2 , we get
$
\frac{b}{2} \times 2=6 \times 2 \Rightarrow b=12
$
Hence, $b=12$ is the solution of the given equation.

$3 I=42$
AnswerWe have, $ 3 l=42$
On dividing both sides by 3 , we get
$
\frac{3 l}{3}=\frac{42}{3} \Rightarrow l=14
$
Hence, $l=14$ is the solution of the given equation.

$x+1=0$
AnswerWe have, $x+1=0$
On subtracting 1 from both sides, we get
$
x+1-1=0-1 \Rightarrow x=-1
$
Hence, $x=-1$ is the solution of the given equation.

Give first the step you will use to separate the variable and then solve the equation.
$x-1=0$
AnswerWe have, $x-1=0$
On adding 1 to both sides, we get
$
x-1+1=0+1 \Rightarrow x=1
$
Hence, $x=1$ is the solution of the given equation.

Check whether the value given in the brackets is a solution to the given equation or not.
$7 n+5=19(n=-2)$
AnswerGiven equation is $7 n+5=19$.
Here, LHS $=7 n+5$
Puting $n=-2$ in LHS, we get
$
\begin{aligned}
& \text { LHS }=7(-2)+5=-14+5=-9 \neq 19 \\
\because & \text { LHS } \neq \text { RHS }
\end{aligned}
$
So, $n=-2$ is not a solution of the given equation.
