Given Equation:
1 - 8x = 4x - x + 12
Solution:
Subtract the Like Terms.
1 - 8x = 3x + 12
Take the RHS to LHS.
1 - 8x - 3x - 12 = 0
Now, Subtract the Like Terms.
-11 - 11x = 0
Now, Take -11 to the LHS.
The value of a number changes when we take something to the other side of the equation.
-11x = 11
x = 11/-11
x = -1
Answer:
x = -1
