Question

Minya is 30 years younger than her mom, and the sum of their ages is 58. How old is Minya?

Answer 1

Let's say that mom is \(m\) years old, then Minya will be \(m - 30\).
We know:\[ m + (m - 30) = 58 \]Solve for \(m - 30\).

Answer 2

I thought that to, but online it says minya is 14 but it doesnt explain how.

Answer 3

I'd explain that.

Answer 4

can you first solve the equation?

Answer 5

Okay if it is m-30 = 58 then you would do the inverse of it which would be 58 - 30 = 28.

Answer 6

?

Answer 7

this is an equation.

Answer 8

\[ m - 30 = 58\]\[ m = 58 + 30\]

Answer 9

58 - 30 = 28

Answer 10

oh sorry 58 + 30 =88

Answer 11

Yeah

Answer 12

\[2m = 88 \implies m = 44 \implies m - 30 = 14 \]
