Equality between the values, equations, or expressions written on both sides.
X difference: 7-2 = 5
y difference: 11-10 = 1
Add up those results: 5+1 = 6
Answer Is 6
Hello from MrBillDoesMath
Answer: 12, 9
Discussion:
Let x be the first number and y the second number. The form the problem statement:
x + y = 21
x - y = 3
Add the two equations. This gives:
(x + x ) + ( y-y) = 21 + 3 =>
2x + 0 = 24 =>
x = 12
Since x -y =3, substituting in the value of x gives, 12 - y = 3 so y = 9
Thank you,
