Solving for x - (6x -5) = 2x+6 2

allochka39001 [22]

we have

$\frac{6x-5}{2}=2x+6$

step 1

Multiply by 2 both sides

$\begin{gathered} 6x-5=2(2x+6) \\ 6x-5=4x+12 \end{gathered}$

step 2

Group terms

$6x-4x=12+5$

Combine like terms

$2x=17$

divide by 2 both sides

$\begin{gathered} x=\frac{17}{2} \\ x=8.5 \end{gathered}$

Verify

substitute the value of x in the original expression

$\begin{gathered} \frac{6(8.5)-5}{2}=2(8.5)+6 \\ 23=23 \end{gathered}$

is ok

the value of x satisfy the equation
