Question

is n=3.5 a solution to the equation 2n=70? yes or no​

Answer 1

Answer:

No.

Step-by-step explanation:

$2n = 70$

Divide both sides by 2:

$n = 35$

35 is the only solution, hence 3.5 is not a solution.

Answer 2

Answer:

NO

Step-by-step explanation:

Given : n = 3.5

Substituting the value inside the equation

2n = 70

2(3.5) = 70

7 ≠ 70

Since LHS≠RHS

We can say that n=3.5 is not a solution for 2n=70
