2. Solve 3x + 6y – 8 = 4 for x
Identify what you are asked to
solve for
3. Solve 3x + 6y – 8 = 4 for x
+8 +8
3x + 6y = 12
Add 8 to both sides
4. Solve 3x + 6y – 8 = 4 for x
+8 +8
3x + 6y = 12
-6y
-6y
Put this off to the side
as to not accidentally
combine with the 12
Subtract 6y from both sides.
5. Solve 3x + 6y – 8 = 4 for x
+8 +8
3x + 6y = 12
-6y
-6y
3x = -6y + 12
Rearrange so the variables
are first, constant is second
6. Solve 3x + 6y – 8 = 4 for x
+8 +8
3x + 6y = 12
-6y
-6y
3x = -6y + 12
