Answer:
3/4
Step-by-step explanation:
Start by simplifying (2x-x) to just (x)
The equation should now look like this: 12+x=9x-6
Now subtract the x on the left side of the equation on both sides.
The equation should now look like this: 12=8x-6
Now add 6 on both sides
The equation should now look like this: 6=8x
To get x by itself you must divide 8 on both sides
The equation should now look like this 6/8=x

Answer:
Step-by-step explanation:
Simplifying
-3a + 8 = 2z + -12
Reorder the terms:
8 + -3a = 2z + -12
Reorder the terms:
8 + -3a = -12 + 2z
Solving
8 + -3a = -12 + 2z
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-8' to each side of the equation.
8 + -8 + -3a = -12 + -8 + 2z
Combine like terms: 8 + -8 = 0
0 + -3a = -12 + -8 + 2z
-3a = -12 + -8 + 2z
Combine like terms: -12 + -8 = -20
-3a = -20 + 2z
Divide each side by '-3'.
a = 6.666666667 + -0.6666666667z
Simplifying
a = 6.666666667 + -0.6666666667z
