Solve the system of equations
(?1,x1)=(−89,−89)(?2,x2)=(89,89)
Evaluate
{x2=89x=?
Solve the equation for x
More Steps
Evaluate
x2=89
Take the root of both sides of the equation and remember to use both positive and negative roots
x=±89
Separate the equation into 2 possible cases
x=89x=−89
{x=89∪x=−89x=?
Evaluate
{x=89x=?∪{x=−89x=?
Calculate
More Steps
Evaluate
{x=89x=?
Substitute the given value of x into the equation x=?
89=?
Swap the sides of the equation
?=89
Calculate
