43-x43 - 5 59 Add 5 to both sides Divide both sides by 4 Now we use the principle of fraction exponents to radicals We use the principle of even roots in this case 4th roots. If an equation is true after the variable has been replaced by a specific number then the number is called a solution of the equation and is said to satisfy it. -1 or 72 which satisfies the above equation.
So x equals 6 does satisfy our equation it is a solution and actually as well see in the future the solution to this equation right over here.
Equation solving Tips for entering queries. 5 2 7 5 2 7 is true so x 5 is a solution. Enter your queries using plain English. How to determine if an equation has one solution which is when one variable equals one number or if it has no solution the two sides of the equation are not equal to each other or infinite solutions the two sides of the equation are identical.
