Answer:

#x = 54 - (5q)/3#

Explanation:

#3x + 5q + 18 = 180#
#3x = 162 - 5q#
#x = (162 - 5q)/3#
#x = 54 - (5q)/3#

Because there are two variables (unknowns in the equation) but there is only one equation, the answer must contain one of the variables. That's why "q" is still in the equation when you find the value of x.

Answer:

This is as far as you can simplify for #x#:

#x=54-(5q)/3#

Explanation:

My calculations are shown below:

#3x+5q+18 = 180#

#3x+5q = 162#

#3x = 162-5q#

# x= (162-5q)/3#

#x=54-(5q)/3#
