Question

When 0.5(20x – 50y + 36) – 0.25(–100x + 40y – 12) is simplified, what is the resulting expression?

Answer 1

`35x - 35y + 21`

solution,

`0.5(20x - 50y + 36) - 0.25( - 100x + 40y - 12) \\ = 10x - 25y + 18 + 25x - 10y + 3 \\`

Combine the like terms:

`= 10x + 25x - 25y - 10y + 18 + 3 \\`

Simplify:

`35x - 35y + 21`

Hope this helps...

Good luck on your assignment...
