Question

Solve the given equation for s:
$\frac{s}{3}+4=5$

• A. 3

Answer 1

The correct option is A 3
The given equation can be solved by using subtraction and multiplication operations.
Subtracting 4 on both sides of the equation we get,
$\Rightarrow \frac{s}{3}+4-4=5-4\Rightarrow \frac{s}{3}=1$
Now, multiplying both the sides of the equation by 3, we get
$\Rightarrow \frac{s}{3}=1\Rightarrow \frac{s}{3}\times 3=1\times 3\Rightarrow s=3$
