Jabulani think of a number × Sihle multiplies this number by 6 and John multiplies it by 3 and adds 9 Sihle and John they get the same answer so What number did Jabulani think of?
6x
=
3x + 9
is
6x = 3x + 9
3x = 9
x = 3
Let's work through this step-by-step.
Let's start by saying the number that Jabulani thought of is "x".
Sihle multiplies this number by 6, so we get 6x.
John multiplies it by 3 and adds 9, so we get (3x + 9).
According to the given information, Sihle and John got the same answer, so we can set up the equation:
6x = 3x + 9
Now, let's solve this equation:
Subtract 3x from both sides:
6x - 3x = 3x - 3x + 9
3x = 9
Divide both sides by 3:
3x / 3 = 9 / 3
x = 3
Therefore, the number that Jabulani thought of is 3.
