Step-by-step explanation:
I think you can solve this question now
Answer:
4x - 2y = -8--------equation 1
y = 2x + 4
or, -2x+y=4---------equation 2
multiply equation 2 by 2 and solving equation 1and2 we get,
4x - 2y = -8
-4x+2y=8
---------------=
impossible
The formula for x in terms of other terms in the equation is; x = (cz-yw)/(y-c).
<h3>What is the formular for x in term of other terms in the equation?</h3>
According to the task content, it follows that the variable X is to be made the subject of the formula;
Hence, it follows that;
y ( x + w ) = c ( x + z )
yx +yw = cx +cz
x(y-c) = (cz-yw)
x = (cz-yw)/(y-c)
Remarks: The complete question requires that x be made the subject of the formula.
