System of Equations: Solve for (x,y) given the system of linear equations "X 1 point
Elenna [48]

Answer:

  (x, y) = (4, 0)

Step-by-step explanation:

It looks like you want to solve ...

  • x - y = 4
  • x + y = 4

Adding the two equations gives ...

  2x = 8

  x = 4 . . . . divide by 2

Then ...

  y = 4 - x = 0

The solution is (x, y) = (4, 0).

_____

If you think about what you're seeing when you read the equations, you realize that adding or subtracting y gives the same result. Hence y=0 and x=4.

All the fraction that are greater than 1\2
never [62]
Hi There!

Change all the fractions to decimal you do that by dividing numerator by the denominator. Remember \frac{1}{2}   as a decimal is 0.5

A=  \frac{3}{7}  =    0.43

B=  \frac{5}{9}  =    0.60

C=  \frac{8}{10} =   0.8

D=   \frac{5}{12} =   0.42

E=    \frac{3}{5}   =   0.6

Based, on the data above B,C,E are greater than \frac{1}{2} because they all have decimals greater than 0.5, B= 0.6, C= 0.8, E=0.6

So, \frac{5}{9} ,\frac{8}{10} ,\frac{3}{5}  are all greater than \frac{1}{2}

Hope This Helps :)

Solve the equation -9v-9=-27 for v.
Nikolay [14]

Answer:

v=2

Step-by-step explanation:

-9v-9=-27

add nine to both sides

-9v-9+9=-27+9

simplify

-9v=-18

divide both sides by -9

-9v/-9   -18/-9

simplify y=2

hope this helps :) have a nice day !!
