Solve using elimination.
4x + y = -5
8x + 3y = -19
Plz I need help

(1, -9)

Step-by-step explanation:

4x + y = -5

8x + 3y = -19

If we have to use elimination, that means we're going to add or subtract these two whole equations by each other so that we can cancel out one of the variables.

I think that we could easily turn 4x into 8x if we multiply the top equation by 2.

4x + y = -5 ---> 8x + 2y = -10

Now put them next to each other, and subtract to get rid of the xs.

  8x + 2y = -10

-  8x + 3y = -19

  0x - y = -10 - -19

  -y = 9

   y = -9

Plug this back in to get x.

  4x + y = -5

  4x - 9 = -5

  4x = -5 - -9

  4x = 4

  x = 1

definition: a circle is the  set of all points in a plane that are equidistant  from a given  point  called the center of the circle. we use the symbol ⊙ to represent a circle. the a line segment from the center of the circle to  any point  on the circle is a radius of the circle.

i googled it and this is what i got i don't know how it is. sorry.

the equation for this situation is y=122+45. to solve the equation you would add 45 and 122 to get a total of 167lbs. in conclusion, grace's weight eight weeks ago was 167lbs.
