What is 15x-10 equals -9x plus 2?

Answer 1

15X - 10 = - 9X + 2

add 9X to both sides

15X + 9X - 10 = - 9X + 9X +2

24X - 10 = 2

add 10 to each side

24X - 10 + 10 = 2 + 10

24X = 12

divide each sides integer by 24

(24/24)X = 12/24

X = 1/2

------------check in original equation

15(1/2) - 10 = - 9(1/2) + 2

15/2 - 10 = - 9/2 + 2

Now, 10 is 20/2 and 2 is 4/2

15/2 - 20/2 = - 9/2 + 4/2

- 5/2 = - 5/2
