1 + 5 x 25 = 126

5 + 2 = 7

25 - 5 + 1 = 21

25 + 25 + 25 = 75

1)
a + a + a = 75
a = 75 / 3 = 25

2)
a - b + c = 21
25 - b + c = 21
-b = 21 - 25 - c
b = -(21 - 25 - c)
b = -( -4 - c)
b = 4 + c

3)
b + 2c = 7
4 + c + 2c = 7
4 + 3c = 7
3c = 7 -4
3c = 3
c = 3 / 3 = 1

Now : b = 4 + c = 4 + 1 = 5

4)
c + b x a = ?
1 + 5 x 25 = 126

My wife says 101..

P.S. She's a Math teacher.

so she should know * and / are always before + and -  if there is no ()    :)

25 + 25 + 25 = 75

25 - 5,5 + 1,5 = 21

5,5 + 1,5 = 7

1,5 + (5,5 x 25) = 139  <>

( 1,5 + 5,5 ) x 25  = 175  <>
