A variable needs to be eliminated to solve the system of equations below. Choose the correct first step.
-3x + 4y = -50
3x + 3y = -6

The variable that needs to be eliminated in these systems of equations are 3x

Step-by-step explanation:

-3x + 4y = -50

3x + 3y = -6

*solve from top to bottom, if that makes sense, so add 3x to -3x, 4y to 3y, and -50 to -6.*

0 + 7y = -56

7y = -56

*divide by 7 to get y alone*

y = -8

plug y into one of the original equations to get x

-3x + 4y = -50

-3x + 4(-8) = -50

-3x - 32 = -50

     +32    +32

-3x = -18

x = 6

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.

on a coordinate grid, point a is at (−4.0, −2.4) and point b is at (4.0, −2.4). point b is a reflection of point a across the –axis. input either a lowercase x or i think is the right awnser
