Question

what is the answer 10x−5y=15

Answer 1

Answer:

if you want to solve for x=1.5

if you want to solve for y=3

Answer 2

Answer:

y = -3 + 2x

x = 3/2 + 1/2y

x = 3/2

Step-by-step 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.
