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.
