What is the value of x in 4x + 3y +15 2X - 5y+1

Question

Using elimination, what is the value of x and y in the following:  4x + 3y = 15

                                                                                            2X - 5y = 1

Answer 1

Hey Joy -- we may double the 2x -5y =1 and subtract it from 4x +3y = 15 ... 13y = 13 ...

 

y=1, x=3 or (3,1) solves ... All the best, ma'am :)
