    8x    -   2y = 5     multiply  by 3
-12x     + 3y  = 7      multiply by 2   giving:-

24x  - 6y  = 15
-24x + 6y = 14

adding these 2 equations:-

0 = 29

This is nonsense So there are no solutions to this system of equatios

Are you sure you have the question right?

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression? 10 x minus 25 y + 18 minus 25
yaroslaw [1]

Answer:

The answer to your question is   35x - 35y + 21

Step-by-step explanation:

Data

Simplify    0.5(20x - 50y + 36) - 0.25(-100x + 40y - 12)

Expand

                       10x - 25y + 18 + 25x - 10y + 3

Group like terms

                      (10x + 25x) + (-25y - 10y) + (18 + 3)

Result

                      35x - 35y + 21

The answer is the last choice
