Answer:
Step-by-step explanation:
x=84/5
1. Multiply both sides by 2/1. New equation: 84/x=5/1
2. Multiply both sides by x. New equation: 84=5x
3. Divide both sides by 5. New equation: 84/5=x
Answer:
x=16.8
Step-by-step explanation:
We will have to solve this question by Cross multiplying
So let's solve the given question
42/x=5/2
So let's cross multiply
42×2=5x
84=5x
We will have to make x the subject of formula by dividing both sides by 5
x=16.8
Therefore the final answer is 16.8
