Elias had 3 time as much money as munah. Elias spent $240 and munah received $60 from her brother. In the end. Elias and munah had the same amount of money. How much did elias have at first

$450

Step-by-step explanation:

let m represent the amount of money munah has

That means elias would have 3 * m or 3m dollars.

Then, you have m + 60 = 3m - 240

solve:

So munah started with $150. Since elias has 3 times as much, they have 150 * 3 = 450

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
