Question

Your aunt is 37 years old. This is 7 less than 4 times your brother's age. Write and solve an equation to find your brother's age A.

I'm confused on what the equation will be.. please help me solve this. :)

Answer 1

Brother's age is 11

Explanation:

37 = 4a - 7 where x is the brother's age

isolate the a:

4a - 7 = 37

4a = 44

a = 11

Brother's age is 11
