3x=x+82x-7=13-18x28-x=3x-8410x-3=x+15x+6=3x5x+15=x-492x+3=3x-27x+8=4x-103x-2=x-47x=5x+4

Answer 1

$7x=5x+4$

start by susbtracting 5x on both sides of the equation in order to get all x terms one side and all constants in the other side

$\begin{gathered} 7x-5x=5x-5x+4 \\ 2x=4 \end{gathered}$

now divide both sides by 2 in order to obtain the value of x

$\begin{gathered} \frac{2}{2}x=\frac{4}{2} \\ x=2 \end{gathered}$
