Which equation results from adding the equations in this system?

Mathematics

Answer: 3x=3

Step-by-step explanation: Let's divide this into parts--

1. Adding the x variables: -2x+5x or 5x-2x = 3x.

2. Adding the y variables: y-y or -y+y = 0. (The negative and the positive y cancel each other out.)

3. Adding the numbers: 8-5 or -5+8 = 3.

Now just put it back into an equation: 3x + 0 = 3.

We don't need to add the 0, so the equation changes into 3x = 3.

deff fn [24]

Answer:

Step-by-step explanation:

\frac{2x - 5}{5} + x - 2 = 3(x + 5)

\frac{2x - 5}{5} + x - 2 = 3x + 15

\frac{2x - 5}{5} = 2x + 17

2x - 5 = 10x + 85

-8x = 90

x = \frac{-45}{4}
