Question

Give the steps you will use to separate the variable and then solve the equation: $5m+7=17$.

Answer 1

Step 1: Subtraction

The given equation is $5m+7=17$.

Subtracting $7$ from both sides of the equation we get,

$5m+7-7=17-7$

$\Rightarrow$ $5m=10$

Step 2: Division

Dividing $5$ from both sides of the equation we get,

$\frac{5m}{5}=\frac{10}{5}$

$\Rightarrow$$m=2$

Hence, the solution of the given equation is $m=2$.
