$x=5$

$7x-2=3x+18$

Rearrange the equation putting the numbers on one side and the pronumerals on the other side
$7x-3x=18+2$

Simplify
$4x=20$

Divide both sides by 4
$x=5$

$x=5$

Given -

$7x-2=3x+18$

Add $-3x$ on both sides

$7x-2-3x=3x+18-3x$
$7x-2-3x=cancel(3x)+18cancel(-3x)$
$4x-2=18$

Add $2$ on both sides

$4x-2+2=18+2$
$4xcancel(-2)cancel(+2)=18+2$
$4x=20$

Divide both sides by $4$

$(4x)/4=20/4$
$(cancel4x)/cancel4=20/4$
$x=5$
