Answer:
x = 21.6
Step-by-step explanation:
Solution by Cross Multiplication
For the equation
35=x36
The cross product is
3×36=5×x
Solving for x
x=3×365
and reducing
x=21.6
Solution by Proportion
Since the equation is an equality
If
36 ÷ 5 = 7.2
Then it is true that
x ÷ 3 = 7.2
Solving for x
x = 3 × 7.2
x = 21.6
