You are given the X value, replace x with 2 in the first equation to solve for y:
y=2x +3
y = 2(2) +3
y = 4+3
y = 7
Now replace y with 7 and x iwth 2 in the second equation and solve for k:
y = -x +k
7 = -2 +k
Add 2 to both sides:
9 = k
so k = 9
The point is given as k-2, which is 9-2 = 7, which is what y equals in the first equation.
K = 9
It's easy you just need to multiply both numbers by 25
Yes becaus any even numbers can be represented as 2n where n is an integer
so 2n and 2m where m and n aer both integers
they both have 2 as a factor so that will be included in finding the greatest common factor
