Question from Muhammed, a student: A x 4 = E |
Hi Muhammed,
For the first equation $A \times 4 = E,$ solve for $A$ in terms of $E.$
For the second equation $A \div 4 = E,$ solve for $B$ in terms of $E.$.
Do the same for the third and fourth equations. Substitute into $A+B+C+D = 100$ and solve for $E.$
