More Steps

Evaluate
5−144x4=0
Move the constant to the right-hand side and change its sign
−144x4=0−5
Removing 0 doesn't change the value,so remove it from the expression
−144x4=−5
Change the signs on both sides of the equation
144x4=5
Divide both sides
144144x4=1445
Divide the numbers
x4=1445
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±41445
