Question

solve the following linear equations by trial and error method​

Answer 1

Answer:

ans is 3

Step-by-step explanation:

In trial and error method we change the value of x.So let's try changing the value with different numbers.

we have, 5x-2=13

lets change with first taking 2 in place of x

5(2)-2=13

10-2=8

So as we noticed the value didn't came 13 so we will try with other number.

5(3)-2=13

15-2=13

Thus,we got the same value as given so 3is the answer.

Hope it helps!
