Question
Solve the equation
x1=−4725,x2=4725
Alternative Form
x1≈−5.18901,x2≈5.18901
Evaluate
13−x4=712
Separate the equation into 2 possible cases
13−x4=71213−x4=−712
Solve the equation for x
More Steps
Evaluate
13−x4=712
Move the constant to the right-hand side and change its sign
−x4=712−13
Subtract the numbers
−x4=699
Since the left-hand side is always negative or 0,and the right-hand side is always positive,the statement is false for any value of x

Evaluate
13−x4=−712
Move the constant to the right-hand side and change its sign
−x4=−712−13
Subtract the numbers
−x4=−725
Change the signs on both sides of the equation
x4=725
Take the root of both sides of the equation and remember to use both positive and negative roots
