=3x - 7 = 15 - 3x (as we multiplied 3 with 5 and -x)
=3x + 3x [reciprocal of sign and x as 3x and - 3x are having same variable] = 15 + 7 [ reciprocal of sign and number as both of them don't have a variable]
= 6x = 22
= x = 22/6 [reciprocal of numbers]
= x = 11/3 [we can convert it into mixed fraction. As per ICSE Council, it's compulsory to convert it into mixed fraction]
Therefore, x = 3 integer 2/3
Or, x = 3.66....
Hopefully it helps you!
