See a solution process below:

Explanation:

Subtract #color(red)(18)# and #color(blue)(3x)# from each side of the equation to solve for #x# while keeping the equation balanced:

#-color(red)(18) + 18 + 4x - color(blue)(3x) = -color(red)(18) + 172 + 3x - color(blue)(3x)#

#0 + (4 - color(blue)(3))x = 154 + 0#

#1x = 154#

#x = 154#
