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

How do you know if you will subtract or add in simplifying algebraic expressions?
Only like terms can be subtracted or added in algebraic expressions.
How do you add similar rational algebraic expressions?
Lcd/lcm
After you add or subtract two rational expressions it's a good idea to see if you can your answer?
reduce
How do you evaluate expressions with fractions?
Add, subtranct, multiply, divide, do whatever the expression calls for.
Two angles that add to 180 degrees?
When two angles add up to 180 degrees, they are supplementary to each other.
How do you solve an algeraba problem?
There are lots of different types of problems in algebra; you have to learn each type separately. For example, how to add similar expressions; how to multiply expressions; how to factor polynomials; how to solve equations; etc.

To add two rational expressions that have the same denominator you simply add the?
You add the numerators and put over the denominator.

How do you Add rational expressions with common denominators and binomial numerators?
If the denominator is the same, you just add the numerators - just as with plain numbers.
When you add the numbers diagonal from each other in each box on your number chart is there a pattern that exists?
Yes, there is.
What do waves do when there in phase?
Waves in phase add to each other and become stronger.
Two angles that add to 180 degrees?
When two angles add up to 180 degrees, they are supplementary to each other.
How do you find two number next to each other which add and multiply?
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.

What is it called when waves combine with each other?
When waves combine with each other, it is called interference. Interference can be constructive, where the amplitudes of the waves add up, or destructive, where the amplitudes cancel each other out.
