Examples from Linear Equations Solver

Simple Linear Equation

"2x + 5 = 13"

Solution: Subtract 5 from both sides, then divide by 2. Answer: x = 4

Variable on Both Sides

"3x - 4 = 2x + 1"

Solution: Subtract 2x from both sides, add 4 to both sides. Answer: x = 5

System of Equations

"x + y = 12, x - y = 4"

Solution: Add equations to eliminate y, solve for x, substitute back. Answer: x = 8, y = 4

Three Variable System

"3x + 2y - z = 7, x - y + z = 3, 2x + y + z = 10"

Solution: Use elimination method to reduce to 2x2 system, then solve systematically.
