Ronelyse is 4 years older than Preston. The sum of their ages is 10. Create a system of equations to solve for their ages

In the system, y will represent Ronelyse's age while x will represent Preston's age.

Y=X+4

X+Y=10

If you were solving this system, you'd use substitution and it would look like this:

X + (X+4) = 10.

The second step would be to get rid of the four by subtracting it from both sides of the equation which would then make it look like this: 2x=6 (I just combined like terms for x)

The third step is to divide both sides by two to get rid of the two. After this step we could find that x=3.

Our fourth step is to put this into our first equation of the system which would make it y=3+4. Then we'd know that y=7

So, Ronelyse (the y) is 7 and Preston (the x) is 3
