Answer:

y = -3 + 2x

x = 3/2 + 1/2y

x = 3/2

Explanation:

If you need what y is equal to:

10x - 5y = 15

-10x -10x

----------------------

-5y = 15 - 10x

----- ----------

-5 -5

y = -3 + 2x

If you need what x is equal to:

10x - 5y = 15

+5y +5y

----------------------

10x = 15 + 5y

----- ----------

10 10

x = 15/10 + 5/10 y

Simplify by 5:

x = 3/2 + 1/2y

10x + (-3 + 2x) = 15

12x - 3 = 15

+3 +3

-----------------

12x = 18

----- -----

12 12

x = 9/6 = 3/2

Hope this helped.
