2x + 7y = 4.....multiply by 2
-4x - 3y = 14
------------------
4x + 14y = 8 (result of multiplying by 2)
-4x - 3y = 14
----------------add
11y = 22
y = 2

2x + 7y = 4
2x + 7(2) = 4
2x + 14 = 4
2x = 4 - 14
2x = - 10
x = -5

solution is : (-5,2)

Step-by-step explanation:

While all three of these include mixtures of two or more things, a suspension can typically be re-separated by using a centrifuge and a solution can be filtered out. A colloid on the other hand, cannot typically be separated after it is put together.

AlexFokin [52]
<em>Hello there, and thank you for asking your question here on brainly.

Why?

You can find this out by dividing 48 and 16. The number you get from it is how much 16s are in 48, which is the answer to our question. (48 / 16 ==> 3) Check: 16 * 3 = 48. This is correct.

Hope this helped you! ♥</em>
