solve for x and y ,32base x+51base y and 23base x +42 base y =710. ,number bases interms of simultaneous equation​
In-s [12.5K]

Answer:

<h2>x = -348.5, y = 350.5</h2>

Step-by-step explanation:

32base x means 3x + 2

Similarly, 32base x+51base y equals to 3x + 2 + 5y + 1 = 3x + 5y + 3

and 23base x +42 base y means 2x + 3 + 4y + 2 = 2x + 4y + 5

As per the given condition, 3x + 5y + 3 = 2x + 4y + 5\\x + y = 2

Putting, y = 2 - x in 2x + 4y + 5 = 710, we get

2x + 4y = 705\\2x + 4(2 - x) = 705\\8 - 2x = 705\\4 - x = 352.5\\x = -348.5

y = 2 - x = 2 - (-348.5) = 2 + 348.5 = 350.5

Simplify this expression<br> 10a + 6x-2a-3x
kondor19780726 [428]

Answer:

3x+8a

Step-by-step explanation:

Given the following question:

10a+6x-2a-3x

In order to find the answer, we combine like terms and then simplify.

10a+6x-2a-3x
=6x-3x+10a-2a
6x-3x=3x
10a-2a=8a
=3x+8a
3x+8a

Hope this helps.
