See a solution process below:

First, combine the like terms on the left side of the equation:

#8color(red)(x) + 9color(red)(x) = 34#

#(8 + 9)color(red)(x) = 34#

#17x = 34#

Now, divide each side of the equation by #color(red)(17)# to solve for #x# while keeping the equation balanced:

#(17x)/color(red)(17) = 34/color(red)(17)#

#(color(red)(cancel(color(black)(17)))x)/cancel(color(red)(17)) = 2#

#x = 2#
