In the diagram below, line l is parallel to line m, and line w is a transversal. If m∠2 = 3x + 17 and m∠3 = 5x − 21, what is m∠3? PLEASE I NEED AN ANSWER FAST. Sorry I this it Geometry and I cant fix it

To solve this system of equations by elimination, what operation could be used to eliminate the y-variable and find the value of x? 6x + 5y = 2 4x + 2y = 8 a) subtract 2 times the second equation from 3 times the first equation b) subtract 3 times the second equation from 2 times the first equation c) subtract 5 times the second equation from 2 times the first equation d) subtract 2 times the second equation from 5 times the first equation
