Answer:
Step-by-step explanation:
4x+y=14
x-2y=8
then;
x=8-2y
substitute;
4(8-2y)+8-2y=14
32-8y+8-2y=14
40-10y=14
26=10y
y=2.6 , work out 4x+2.6=14 to get x
I think the answer is N-4
Answer:
400
$1 = 100p
$1 x 4 = 100 x 4
= 400p
Would love a brainliest - just need one more to get to the next level!
Answer:
This how you get x. First the way to find the answer is to first put 5x by itself by canceling it out and putting it on the other side of the = which will be
5x-(x-18)=
-5x -5
Which then gets you this
-(x-18)=-5x
After that its
x-18=-5x
once you have this subtract x
x-18=-5x
-x -x
-18=-6x
Then it leaves you the easy part of just dividing
-18/-6x=-6x/-6x
After dividing you get x to be 3
x=3
Once you have x=3 input that number into your equation and you get the answer.
Hope this helps

Answer:</h3>
x = -5/2
<h3>Explanation:</h3>
<u>Given</u>
(2x+1)/(x-2) + 4/x= -8/(x^2-2x)
<u>Find</u>
x
<u>Solution</u>
We note that the denominators in this equation are x and x-2. The solution set must exclude these values, as the equation is "undefined" for those values of x.
__
Multiply by x(x-2)
x(2x+1) +4(x-2) = -8
2x² +5x = 0 . . . . . . . . . . add 8, eliminate parentheses
x(2x +5) = 0
The solutions are the values of x that make these factors zero:
x = 0 . . . . must be excluded
x = -5/2
The solution to the equation is x = -5/2.
