#x = 3#

Step 1) Combine like terms on each side of the equation:

#(5x + 2x) - 6 = (15 - 9) + 3x#

#(5 + 2)x - 6 = 6 + 3x#

#7x - 6 = 6 + 3x#

Step 2) solve for #x# on one side of the equation while keeping the equation balanced:

# 7x - 6 + 6 - 3x= 6 + 3x + 6 - 3x#

#7x - 3x = 6 + 6#

#(7 - 3)x = 12#

#4x = 12#

#(4x)/4 = 12/4#

#x = 3#
