Answer: A= 119 and B=109
Explanation:
You need to write two equations to solve this.
A+B=228
B=A-10 (because B had 10 less runs than A)
Because B=A-10, you can plug A-10 into the first equation. That would make it A+A-10=228 or 2A-10=228. (The point of plugging A-10 into the equation is so you have one variable. So this equation would find out how many runs player A has).
Add 10 to both sides of the equation(to get the variable and nonvariable on separate sides). That leaves you with 2A=238.
To isolate A, divide both sides by 2. A=119. Don't forget about the first equation though!! A+B=228, and because A=119, 119+B=228.
A= 119 and B=109
I hope this helped you!1
