Explanation:
65 + 56 + 6x - 1 = 180 original equation
120 + 6x = 180 combine like terms
6x = 60 subtract 120 both sides
x = 10 divide by 6 on both sides
CHECK YOUR WORK:
65 + 56 + 6 (10) - 1 = 180
121 + 60 - 1 = 180
181 - 1 = 180
x = 10
Answer:
65+56+6x-1=180
= 121 + 6x - 1 = 180
-121 -121
= 6x - 1 = 59
+1 +1
= 6x = 60
/6 /6
Check My Work:
65+56+60-1=180
121+60-1=180
120+60=180
