Question

Examine the system of equations.
5x + 6y = 32
5x - 6y = 8
Which variable or variables will be eliminated when you
add the system of equations?
Which equation results from adding the system of
equations?

Answer 1

Y  and   10x=40

the other guy just put this                                                                                      Examine the system of equations.

5x + 6y = 32

5x – 6y = 8

Answer 2

10x = 40

The variable y is eliminated.

What are some examples of equations?

There are following 3 types of polynomial equations:

• Monomial Equations
• Binomial Equations
• Trinomial Equations

How do you evaluate an equation?

• ∫ y2+y−2dy ∫ y 2 + y − 2 d y
• ∫ 2 1 y2 +y−2dy ∫ 1 2 y 2 + y − 2 d y
• ∫ 2 −1 y2 +y−2dy ∫ − 1 2 y 2 + y − 2 d y

To add a system of equations, we add the common terms. x with x, y with y, and values with values.

In this question:

5x + 6y = 32

5x – 6y = 8

Adding:

5x + 5x + 6y - 6y = 32 + 8

10x = 40

hence the variable y is eliminated.
