Answer 1

${\huge{\sf{\green{\underline{\underline{Question}}}}}}$

solve 3(x-1) = 8 with verification

━━━━━━━━━━━━━━━━━━━━

${\huge{\sf{\green{\underline{\underline{Solution}}}}}}$

multiply 3 with the bracket.

3x - 3 = 8

now, transfer 3 to RHS

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

3x = 11

x = 11/3

━━━━━━━━━━━━━━━━━━━━━

${\huge{\sf{\green{\underline{\underline{Verification}}}}}}$

Put x = 11/3 in the equation (1)

3(11/3) = 8 + 3

11 = 11

LHS = RHS

Hence, it's verified.

Answer 2

Answer:

3x- 3 = 8

3x = 8 + 3

3x = 11

x = 3/11

verification:

x = 11/3

3 [ ( 11/3 )-1 ] = 8

33/3 -3 = 8

11-3 = 8

8 = 8
