To solve this, set up two equations using the information you're given. Let's call our two numbers a and b: 1) D<span>ifference of two numbers is 90 a - b (difference of two numbers) = 90
2) The quotient of these two numbers is 10 a/b (quotient of the two numbers) = 10
Now you can solve for the two numbers. 1) Solve the second equation for one of the variables. Let's solve for a: a/b = 10 a = 10b
2) Plug a =10b into the first equation and solve for the value of b: a - b = 90 10b - b = 90 9b = 90 b = 10
3) Using b = 10, plug it back into one of the equations to find the value of a. I'll plug it back into the first equation: a - b = 90 a - 10 = 90 a = 100
