To solve this system of equations by elimination, what operation could be used to eliminate the x-variable and find the value of y? 6x +5y=10 4x +2y = 8

Pls brainliest will be awarded if answer is correct

2. explain in words how you plot the point (4, −2) in a rectangular coordinate system.

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.
