x=01−4x=0
Solve the equation
More Steps

Evaluate
1−4x=0
Move the constant to the right-hand side and change its sign
−4x=0−1
Removing 0 doesn't change the value,so remove it from the expression
−4x=−1
Change the signs on both sides of the equation
4x=1
Divide both sides
44x=41
Divide the numbers
x=41
x=0x=41
x=0x=0x=41
Find the union
x=0x=41
Solution
x1=0,x2=41
