Solution:

8x+4 = 3(x-1)+7

=> 8x+4 = 3x-3+7

=> 8x+4 = 3x+4

=> 8x-3x = 4-4

=> 5x = 0

=> x = 0

Verification:

Substitute x = 0 , we get

LHS = 8×0 + 4

= 4

RHS = 3(0-1)+7

= -3+7

= 4

Therefore,

LHS = RHS

SOLUTION :-

8x + 4 = 3(x - 1)  + 7

8x  + 4 = 3x - 3 + 7

8x + 3x =  - 3 + 7 - 4

5x =  - 7 + 7

5x = 0

x  = \frac{0}{5}

x = 0

check \: 8x + 4 = 3(x - 1) + 7

LHS \:  = 8x + 4 = RHS \:  = 3(x - 1) + 7

LHS = 8 \times 0 + 4 = RHS \:  = 3(0 - 1) + 7

LHS = 0 + 4 = RHS = 3(1) + 7

LHS = 4 = RHS = 4

LHS  = RHS

Hence checked
