WebAlgebra Examples Step-by-Step Examples Algebra Systems of Equations Solve by Substitution x + 2y = 4 x + 2 y = 4 , x − y = −3 x - y = - 3 Subtract 2y 2 y from both sides of … WebYou could choose whatever values you like for all but one of the variables, and then final variable can always be made to fit. For example, if you had the equation ax + by + cz = k, then whatever you pick for y and z, you can solve for x to get x = (k - by - cz)/a, and the equation will be satisfied.

WebSolving Linear Equations Example 1: Solve x = 12 (x +2) Solution: x = 12 (x + 2) x = 12x + 24 Subtract 24 on both sides of equation x – 24 = 12x + 24 – 24 x – 24 = 12x Simplify 11x = -24 Isolate x: x = -24/11. Example 2: Solve x – y = 12 and 2x + y = 22 Solution: Name the equations x – y = 12 … (1) 2x + y = 22 … (2) Isolate Equation (1) for x, WebAlgebra Examples. Step-by-Step Examples. Algebra.
