You can put this solution on YOUR website! ----------------------------
Thando’s dad is three times as old as she is now. Ten years ago he was seven times as she
was old then.
----------------------------
NOW : Thando now is x years old;
Her dad is 3x years old.
TEN YEARS AGO
7*(x-10) = 3x-10.
Simplify and solve
7x - 70 = 3x - 10
7x - 3x = 70 - 10
4x = 60
x = 60/4 = 15.
ANSWER. Thando is 15 years old; her dad is 3*15 = 45 years old.
