Explanation:
The first step is to distribute the bracket on the right side.
#2+3x=4x-12# Collect terms in x on the left side and numeric values on the right side.
subtract 4x from both sides.
#2+3x-4x=cancel(4x)cancel(-4x)-12#
#rArr2-x=-12# subtract 2 from both sides.
#cancel(2)cancel(-2)-x=-12-2#
#rArr-x=-14# multiply both sides by - 1
#(-1)xx-x=(-1)xx-14#
#rArrx=14#
#color(blue)"As a check"# Substitute this value into the equation and if the left side equals the right side then it is the solution.
#"left side "=2+(3xx14)=2+42=44#
#"right side "=-2((-2xx14)+6)=-2(-22)=44#
#rArrx=14" is the solution"#
