6x+2=12+8x+6

=>6x+2=8x+18

=>8x-6x=2-18

=>2x=-16

=>x=-16/2

Hence,the value of x is -8

Working out:

Here in this question, we are given with an equation in variable x and we have to find the value of x in this equation.

GiveN:

  • 2(3x + 1) = 12 + 2(4x + 3)

So, let's start solving and understanding the steps followed to get the value for x....?

 \sf{ \longrightarrow{2(3x + 1) = 12 + 2(4x + 3)}}

Opening the parentheses in both sides of the equation,

 \sf{ \longrightarrow{6x + 2 = 12 + 8x + 6}}

Adding the constant terms and like terms,

\sf{ \longrightarrow{6x + 2 = 8x + 18}}

Now as we need to find x in this equation, let's isolate x in any one side of the equation,

\sf{ \longrightarrow{6x - 8x = 18 - 2}}

\sf{ \longrightarrow{ - 2x = 16}}

We know that inverse of multiplication is dividion. So, dividing -2 from both sides,

\sf{ \longrightarrow{ \dfrac{ - 2x}{ - 2}  =  \dfrac{16}{ - 2} }}

\sf{ \longrightarrow{x =  - 8}}

So, the required value for x:

 \huge{ \boxed{ \red{ \sf{ - 8}}}}

And we are done !!

Quick check:

Plug this value of x in the equation:

\sf{ \longrightarrow{2(3 \times ( - 8) + 1) = 12 + 2(4 \times  ( - 8) + 3)}}

Now opening the parentheses,

\sf{ \longrightarrow{2( - 24 + 1) = 12 + 2( - 32 + 3)}}

\sf{ \longrightarrow{2( - 23) = 12 + 2( - 29)}}

\sf{ \longrightarrow{ - 46   =  - 46}}

Here LHS = RHS

✤ Hence, verified !!
