Linear equations and inequalities problems
NettetSolve the linear equations with variables in numerator and denominator, check the solution and determine the conditions of solvability : Solve the linear equations with a parameter a∈R : Solve the linear inequalities : Solve the linear inequalities with absolute value : You might be also interested in: NettetStart with: W × L ≥ 7. Substitute L = 8 − W: W × (8 − W) ≥ 7. Expand: 8W − W2 ≥ 7. Bring all terms to left hand side: W2 − 8W + 7 ≤ 0. This is a quadratic inequality. It can be solved many way, here we will solve it by completing the square: Move the number term −7 to the right side of the inequality: W2 − 8W ≤ −7.

NettetWhat are Linear inequalities? In maths, linear inequalities are the equations in which both sides of the equation are separated by the inequality symbol, such as <, >, ≤ and ≥. That means LHS and RHS are not equal. For example, 2x – 4 < 12, x – y > 7, 3x – 4 ≤ 0, and so on. Also, check: Linear inequalities. Linear Inequalities ...
