Find the solution of this system of equations. separate the x- and y-values with a comma. x= 8 + y -2x + 6y= -20

What is the result of adding the system of equations? 2x+y=4 3x-y=6

How do you determine if an ordered pair is a solution to a given equation?

In each of the cases that follow, the magnitude of a vector is given along with the counterclockwise angle it makes with the +x axis. use trigonometry to find the x and y components of the vector. also, sketch each vector approximately to scale to see if your calculated answers seem reasonable. (a) 50.0 n at 60.0°, (b) 75 m/ s at 5π/ 6 rad, (c) 254 lb at 325°, (d) 69 km at 1.1π rad.
