Answer:
w = -5
Step-by-step explanation:
Hello there!
9+7w-9=5w-10
Add 9 and -9 since we can add those
7w=5w-10
Use subtraction Prop of Equality (combining/simplifying like terms)
2w = -10
Now isolate the w by dividing 2w by 2 and use the division prop of equality 
w = -5

Answer:
bradley is 50 and madison is 23
Step-by-step explanation:
m + 27 = b 
(b - 7) + (m - 7) = 59
[(m + 27) - 7] + (m - 7) = 59 
m + 20 + m -7 = 59
2m + 13 = 59
2m = 46
m = 23, b = 23 + 27 = 50
