How do i solve 6x+2=-2x+22

Mathematics
1 answer:
belka [17]3 years ago

6x+2=-2x+22

Move -2x to the other side

Sign changes from -2x to +2x

6x+2x+2=-2x+2x+22

6x+2x+2= 22

8x+2= 22

Move +2 to the other side

8x+2-2= 22-2

8x= 22-2

8x= 20

Divide both sides by 8

8x/8= 20/8

x= 20/8

Reduce fraction by dividing by 4

20/4= 5

8/4= 2

Answer:

x= 5/2

Find the value of r so the line passes through each pair of points has the give slopes
Art [367]

Answer:

r=64

Step-by-step explanation:

First, let's start with what we have. If we use y=mx+b here's what we can put in:

y=-4x+b

Then we can use one of the given points to find the y-intercept. Since the only complete one is (12,10), we'll use that.

10=-4(12)+b\\10=-48+b\\58=b

So now we have y=-4x+58.

Now we can use our other point with the missing y-value and solve for y.

r=-4(-2)+58\\r=64

So the missing value is 64.

Hope this helps!

( simultaneous equations)
daser333 [38]

Answer:

See method below.

Step-by-step explanation:

m/n + n/3 = 2

2/m + n = 4    

First  eliminate the fractions by multiplying the first equation by 3n:-

3m + n^2 = 6n...........(1)

and the second equation by m:-

2 + mn = 4m..............(2)

Now we solve using substitution:-

From equation  (2):-

4m - mn = 2

m = 2 / (4 - n)

Now substitute for m in equation (1):-

6/ (4 - n) + n^2 = 6n

6 + n^2(4 - n) = 6n(4 - n)

6 + 4n^2 - n^3 = 24n - 6n^2

n^3 - 10n^2 + 24n - 6 = 0

This will not factor so we could solve this using graphical software.

To find the values of the variable m we substitute the found values of n into one of the original equations and solve for m.
