Adding two equations is an easy step. First choose a variable you want to eliminate. Multiply each one by the number that would get you the opposite or additive inverse so it will be gone from the modified equation.
x+y=5 =>3x+3x=15
2x-3x=-5 =>2x-3x =-5
5x =10
x = 2
Substitute that number into one of the equations and solve for the other.
2+y=5
y=3

Any two integers next to each other can add and multiply.There are no two numbersnext to each other because numbers are infinitely dense. that is, between any two numbers there is another, and another, and so on. So there is no "next".Any two integers next to each other can add and multiply.There are no two numbersnext to each other because numbers are infinitely dense. that is, between any two numbers there is another, and another, and so on.
