Matt is 24 and John is 18. 24 - 18 is 6. And 24 + 18 would equal 42.
Answer:
11
Step-by-step explanation:
x+y=8 y=3
x+3=8
-3 -3
x=11
Answer:
21 & 11
Step-by-step explanation:
Let x = first number and y = second number. We need to find the values of x and y, so we need to set up a system of linear equations. The first equation would be x + y = 32 because x and y add up to 32. Then the second equation would be x - y = 10 to represent that the two numbers have a difference of 10. Solving by elimination, we add and get 2x = 42, so x = 21. Then substitute 21 for x in either one of the equations to get y = 11.
