Make your own equation.

Question

1. A number is 6 times another number. The sum of the two numbers is 56.

@. Donna has twice as many coins as Cathy. When Donna gives Cathy 2 coins, they each have the same number. How many coins do they each have?
Let the number of coins that Cathy has be x.

Answer 1

first number : x
second number : 6x

equation: x + 6x = 56

now try the same thing for your second problem

Donna = x coin
Cathy = y coins

x=2y
x-2=y+2
2y-2=y+2

Answer 3
