Hi there!
Maggie is 7 years old.
Let m = Maggie's age
Let her brother's age be represented by (4m - 6)
The ages sum up to 29, therefore:
29 = m + (4m - 6)
Combine like terms:
29 = 5m - 6
Add 6 to both sides:
35 = 5m
Divide both sides by 5:
m = 7.
Answer:
x=7
Step-by-step explanation:
the equation we use to model this expression is x+ (4x-6)=29. This simplifies to 5x-6=29. Add 6 to both sides, and you get 5x=35. Divide both sides by 5 and you get x=7.
