Question

Zach is 4 years older than twice his sister maya's age. zach is 28 years old.

which expression would you use to represent zach's age?

Answer 1

2m + 4 = 28

Explanation:

Let m be Maya's age

1. 4 years older than twice his sister Maya's age = 2m + 4
2. If "4 years older than twice his sister Maya's age" and "Zach is 28 years old" are equal, then this is how you'd write it: 2m + 4 = 28

I hope this helps!

Answer 2

Lets take:

Z - Zach

M - Maya

Now forming the equation:

Z = 2M+4

Z = 28

Solving:

2M+4 = 28

2M = 24

M = 12

Zach's age is 28; whereas Maya's age is 12.
