Answer:

(-1,-6)

Step-by-step explanation:

Plug 6x for y into the bottom equation:

2x+3(6x)= -20

2x+18x= -20

20= -20

x= -1

Substitute -1 for x in the equation for y:

y=6(-1)

y=-6

Can someone help me solve y 12 + y = 4x
Leviafan [203]

Answer: Y = 4x - 12

Step-by-step explanation:

Well, the reason for this is because y can be anything because there are 2 unknown terms in the equation. Thus, the answer to y can be many different answers. The one common thing that all of these answers have is that they have only 1 expression (An equation without equal sign) to solve it. This expression is the answer to y, but it can be changed judging by the answer of x. That is why you cannot determine an exact answer to y with there being many, so you have to write the expression to get y. Which you can find out by:

12 (Part) + y (Part) = 4x (Whole)

So to figure out one part do the whole minus the other part which is why 4x is our answer:

4x (Whole) - 12 (Other Part)

This is called part-whole postulate.

Hope this helps!

How do you find the circumference of a Cylinder with a 7 m radius?
svet-max [94.6K]
The circumference of a cylinder works the same way as the circumference of a circle, as both faces of a cylinder are circles.

The circumference of a circle can be found with the formula C=2 \pi r^{2} where r is the radius.

If you can enter the answer in terms of pi, I would suggest you do that. If not, just multiply by 3.14.

Hope this helps!
