Question

Solve the following equations by systematic method:
(a) 3x - 2x = 3
​

Answer 1

Answer:

3x - 2x = 3

x = 3

after doing subtraction of 2x from 3x you got left with only 1x which can be written as only x

so x = 3

Answer 2

It’s very easy

All you gotta do is subtract 2x from 3x and you will end up with x. So, x will be 3

3x-2x=3
x=3
