Question

Explain what operation should be used to solve the equation 3.5n= 10.5 what is the value of n?

Answer 1

Answer: n = 3

Explanation:

divide 3.5n by 3.5n then divide 10.5 by 3.5 which is

n = 3

Answer 2

`\boxed{\sf{n=3}}`

Explanation:

To find the value of n, you have to isolate it on one side of the equation.

3.5n=10.5

First, multiply by 10 from both sides.

`\sf{3.5n*10=10.5*10}`

Solve.

35n=105

Divide by 35 from both sides.

35n/35=105/35

Solve.

105/35=3

n=3

• Therefore, the final answer is n=3.
