Answer:
x = 1/9
Step-by-step explanation:
We are given the equation:
8x + 2 = 3 - x
In order to solve for the variable x, we need to isolate it; in other words, we need to combine all the x terms and move everything else to the other side.
First, add x to both sides:
8x + x + 2 = 3
9x + 2 = 3
Now subtract 2 from both sides:
9x = 3 - 2 = 1
Divide both sides by 9:
The answer is thus 1/9.

Add x to both sides.
Subtract 2 from both sides.
9x = 1
Divide both sides by 9.
c = unknown
a = 4c
120 = 2a + 2c
120 = 2(4c) + 2c
120 = 8c + 2c
120 = 10c
120/10 = 10c/10
c = 12
