Answer:
x = 69
Step-by-step explanation:
x+x+(x-27) = 180
3x = 207
x = 69
x=12.3
Combine the like terms (add the constants together and add the variables together)
The sum of the variables is 19x and the sum of the constants is -54
Add 54 to 180 and you'll get 234
Divide 234 by 19
The quotient is 12.31579
Round that to the nearest tenth and 12.3 is your answer
