Question

I need help please.

Answer 1

No

Explanation:

No, if you plug in 3 for 70 this happens;

25=70(3)

Seventy times 3 is obviously not 25, therefore, 3 is not a solution of the equation.

Answer 2

Just use the substitution method for the number 3 into 25= 70n

25= 70(3)

25= 210

Answer is No
