Solving equations in two unknowns requires two independent equations. Since you have only one equation there is no solution.

To solve a system of equations, you need equations (number phrases with equal signs).

No It;s Not A Solution > :)

Create a matrix of the coefficients of each equation. The solutions to the equations should make up the rightmost column of the matrix. Then, row reduce the matrix until you are able to rewrite the equations and solve them. The matrix should be a 4x5 matrix (4 rows and 5 columns) for four equations with four variables. This is known as a system of equations.

If: 14x = 56Then x = 56/14Therefore: x = 4

These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.

three things: 1) that the value of 4 is equal to the value of 4. 2) you did not obtain any revealing information. 3) your strategy for solving that system of equations was not good.

you didn't put any equations, but the answer probably begins with y= (x-4)^2+1

You keep switch change when you have two negitvie numbers like -4 + -7 You keep the -4 change the + to a - and change -7 to 7 -4 - 7 is the new problem. and you slove it from there

There are several ways to do it - depending, in part, on the kind of equations. Sophisticated methods exist specifically for linear equations, among others. However, for a start, you can combine equations (1) and (2), eliminating one variable; the same for equations (2) and (3), and for equations (3) and (4) (eliminating the same variable in every case). That leaves you with 3 equations with 3 variables. Similarly, reduce the 3 equations in 3 variables, to 2 equations in 2 variables (eliminating the same variable in every case). Combine those into a single equation with 1 variable. Example for eliminating a variable: (Eq. 1) 5a + 3b - 3c + 8d = 28 (Eq. 2) 8a - 3b + 8c - 6d = 8 If you just add up the equations, you eliminate variable b. If you want to eliminate variable a, multiply the first equation by 8, and the second by (-5), then add the resulting equations.
