Answer 1

       $\underline{\bold{Solution:}}$

       $\text{The given expression is }8x + 4 = 3(x-1) + 7$

       $\text{Simplifying...}$

$\implies 8x + 4 = 3(x) + 3(-1) + 7$

       $\text{Simplifying...}$

$\implies 8x + 4 = 3x -3 + 7$

       $\text{Simplifying...}$

$\implies 8x + 4 = 3x + 4$

       $\text{Transposing }(3x+4) \text{ to L.H.S}$

$\implies 8x + 4 - 3x - 4 = 0$

       $\text{Simplifying...}$

$\implies 5x = 0$

       $\text{Transposing 5 to R.H.S}$

$\implies x= \dfrac05$

       $\text{Simplifying...}$

$\implies \boxed{x = 0}$

Answer 2

Answer:

8x+4=3(x-1)+7=12x=3x-3+7

12x=7x

X=7x/12
