Question

Solve the equation 3n + 7 =25 by trial and error method.

Answer 1

Answer:

n=6

Step-by-step explanation:

as we have to do it by trial and error method then we can take any value of n which satisfies the equation so let us start by

n=1

then 3(1) + 7 =10

so this does not satisfy our equation so we have to continue our process till we get 3n + 7 = 25

but as we can see that when we substitute the value of n=6 in the equation

then 3(6) + 7 = 25

then the value of n= 6 satisfies our equation then 6 is the answer for this equation
