Why can't students check what they have typed before posting it?
It is so cumbersome to translate this gibberish into proper English.
present age:
army ---- x
Thabo --- x+5
in 7 years:
army ---- x+7
Thabo ---- x+5 + 7 = x + 12
x+7 = (3/4)(x+12)
x+7 = 3x/4 + 9
x - 3x/4 = 2
1/4 x = 2
x = 8
Don't know who ay is or where he/she comes into play.
