Solve the following equation and check your result.
Q.6 8x + 4 = 3 (x – 1) + 7
We have
8x + 4 = 3 (x - 1) + 7
or 8x + 4 = 3x - 3 + 7 = 3x + 4
Transposing 3x to the LHS and 4 to the RHS, we get
8x - 3x = 4 - 4 = 0
5x = 0
Dividing both sides by 5:
x = 0
Check :- Putting x = 0 in both LHS and RHS:
LHS :- 8x + 4 = 8(0) + 4 = 4
RHS :- 3(x-1) + 7 = 3(-1) + 7 = -3 + 7 = 4
Hence, LHS = RHS
