X= a number
Twice the sum of a number (x) plus 73 equals 156.
EQUATION:
2(x + 73)= 156
Not sure if you need to solve it too, but here's how to solve:
2(x + 73)= 156
multiply 2 by all in parentheses
(2*x) + (2*73)= 156
2x + 146= 156
subtract 146 from both sides
2x= 10
divide both sides by 2
x= 5
The missing number is 5.
CHECK:
2(x + 73)= 156
2(5 + 73)= 156
2(78)= 156
156= 156
Hope this helps! :)
