21/7 + 3/7 (3x - 5) = -4
drag and drop the statement that shows the solution to the equation into the box.
1.) x = -5 1/7
2.) x = -3 1/9
3.) x = -1 23/49
4.) x = -8/9

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
