ANSWER
For Jamal statement to be true,
[tex]c = \frac{b}{a} [/tex]
EXPLANATION
The given statement is:
ax + b = a(x + c)
We expand the left hand side to obtain,
ax + b = ax + ac
Subtract ax from from both sides of the equation.
b=ac
We know that, a≠0 , so we can divide through by 'a'.
[tex] \frac{b}{a} = c[/tex]
