First, get the radical by itself. Then, square both sides of the equation. Then just solve the rest.
You decide to solve for one of the variables, for example, for "y". What exactly you do would depend on how the variables are related. For example, if you have:x + y = 5 and you want to solve for "y", you subtract "x" on both sides. If you have a product, such as: xy = 10 you divide both sides by "x".
Eliminate the variables that have equal coefficients but opposite in sign.x + 2y = 103x - 2y = 14Or you can work to have one of the variables with equal coefficients but opposite in sign such as:3x + 2y = 5x + y = 2 multiply by -2 to both sides3x + 2y = 5-2x - 2y = -4
Coefficients are the numbers directly in front of a variable. Variables are letters in place of numbers in a mathematical problem . For example the expression, "2x" has a variable and a coefficient. The variable is the letter x, and the coefficient is the number 2. The coefficient is NEVER a letter, and is always a number. Coefficients and variables can be used in both scientific and algebraic expressions.
There are several methods. 1. graphing, then find the intersection. 2. Substitution (take one equation and solve for one variable, substitute that into the 2nd equation) 3. Elimination. Arrange both equations in standard form, arrange so that the coefficients on one of the variables are the same and subtract the 2 equations. 4. Cramer's rule, use matrices to solve.
A calculator can be used to proportions to answer a equation. This is easier to solve when having variables on both sides.
You first have to get rid of the numbers that don't have variables. then you divide by the variable and solve for it.

you cannot solve this without more information. When 3 variables are involved, you need 2 equations to solve for the answers for both variables.
You would solve them in exactly the same way as you would solve linear equations with real coefficients. Whether you use substitution or elimination for pairs of equations, or matrix algebra for systems of equations depends on your requirements. But the methods remain the same.

The variables may have different values.

You need another equation to make this a linear equation so you can solve for both variables. One equation with two variables is not enough to determine the correct answer.

Its a method used to find out the common solution of a pair of linear equations in two variables. For it, just make the coefficients of any one term and if the coefficients are having same signs, subtract both and if they are having different signs, add them up.
