What is the solution of the equation 1 - 4x = -9

Answer 1

To solve the equation 1 - 4x = -9, we want to isolate the variable x.

Step 1: Subtract 1 from both sides of the equation:
1 - 1 - 4x = -9 - 1
-4x = -10

Step 2: Divide both sides of the equation by -4:
-4x / -4 = -10 / -4
x = 2.5

Therefore, the solution to the equation 1 - 4x = -9 is x = 2.5.
