Answer:
8x + 6 = 3
Step-by-step explanation if solving for x
Simplifying
8x + 6 = 3
Reorder the terms:
6 + 8x = 3
Solving
6 + 8x = 3
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6' to each side of the equation.
6 + -6 + 8x = 3 + -6
Combine like terms: 6 + -6 = 0
0 + 8x = 3 + -6
8x = 3 + -6
Combine like terms: 3 + -6 = -3
8x = -3
Divide each side by '8'.
x = -0.375
Simplifying
x = -0.375
There number rounds to 3000 so divide that by 11 and round up your answer
