Answer:
12
Step-by-step explanation:
Answer:
x = 12
Step-by-step explanation:
(7x+4)+(2x+5)+(5x+3) = 180
so if you take out the brackets it would be:
7x+4+2x+5+5x+3 = 180
Then you add the similar variables together which would look like:
14x+12=180
Take away 12 from both sides
14x = 180 - 12
14x = 168
Divide 14 from both sides
x = 168/14
x = 12
