-4x - 28y=56 4x + 14y=-28

Mathematics

ddd [48]4 years ago
4 0
Adding the 2 equations will eliminate x because -4x + 4x = 0
so we get
-14y = 28
y = -2
plug this into the second euqtion:-
4x + 14(-2) = -28
4x  - 28 = -28 
x = 0

answer is x = 0 , y = -2

So for CE, you add CD and DE together = CE.
4x+8+27=6x
4x+35=6x
4x-6x=-35
-2x=-35
x=17.5
Answer is the second one: CE=17.5

For ST, you just add SM and MT.
27+58=85
ST=85

What is the value of 36X negative Y over to when X equals three and Y equals -6
Rus_ich [418]

<u><em>Note:</em></u>

<em>Your question is a little unclear. But, from my understanding, I assume you may be asking the evaluation of the expression 36x - y when x = 3 and y = -6.</em>

<em>so I will solve based on my assumption which anyways would clear your concept.</em>

Answer:

The value of 36x - y when x = 3 and y = -6 will be: 114

Step-by-step explanation:

Given

Assuming the expression

36x - y

To Determine

Evaluate 36x - y when x = 3 and y = -6

Given the expression

36x - y

substitute x = 3 and y = -6 to evaluate the expression

36x-y= 36(3) - (-6)

            = 108+6

            = 114

Therefore, the value of 36x - y when x = 3 and y = -6 will be: 114
