Given :
- ➸4x + 3 = 7x - 3
- ➸7(x - 2) - 8(4 - 3x) = 47
- ➸7(25 - m) - 2m = 2(3m - 25)
To Find:
- The solutions of the following equations and verify them
Solution:
Verification:
- Let's put the value of 2 in the place of x
- Hence proved as L.H.S = R.H.S
Verification:
- Put the value of 3 in the place of x
- Hence proved L.H.S =R.H.S
Verification:-
- put the value of 15 in the place of m
- hence proved as L.H.S =R.H.S
