• 2. the variables satisfy linear constraints, which we can write as Ax ‚ b; 3. the goal is to minimize a linear function of the variables: cTx = c1x1 +¢¢¢+cNxN. Note the similarity between (4) and a standard linear algebra problem. The differences are that, instead of Ax = b we have Ax ‚ b, and instead of solving for x with Ax = b

Unknowns (variables) write as one character a-z i.e. a, b, x, y, z. No matter whether you want to solve an equation with a single unknown, a system of two equations of two unknowns, the system of three equations and three unknowns or linear system with twenty unknowns. Systems with three equations and three variables can also be solved using the Addition/Subtraction method. Pick any two pairs of equations in the Then use addition and subtraction to eliminate the same variable from both pairs of equations. This leaves two equations with two variables--one...

Section 3.1 Solving One Step Equations A1.1.4 Solve simple equations in one variable using inverse relationships between operations such as addition and subtraction (taking the opposite), multiplication and division (multiplying by the reciprocal), raising to a power and taking a root; the field variable is described by the approximate relation φ(x, y) = N 1 (x, y) φ 1 + N 2 (x, y) φ 2 + N 3 (x, y) φ 3 where φ 1, φ 2, and φ 3 are the values of the field variable at the nodes, and N 1, N 2, and N 3 are the interpolation functions, also known as shape functions or blending functions.
To solve an equation is to find the set of all solutions of the equation. Example 1. x 2 - 9 = 0. This equation has two solutions, x = 3 and x = -3. For some equations the set of solutions is obvious. Example 2. x = 3. It is clear that the number 3 is the only solution for this equation. For example, to solve the system of equations x + y = 4, 2x - 3y = 3, isolate the variable x in the first equation to get x = 4 - y, then substitute this value of y into the second equation to get 2(4 - y) - 3y = 3. This equation simplifies to -5y = -5, or y = 1. Plug this value into the second equation to find the value of x: x + 1 = 4 or x = 3.
