ProcedureMathematical Procedure
(Algorithm)
2x = -8
1. One negative x is equal to 52. Take the opposite of each side of the equation3. One x is equal to five negative units
3x = 2 + x -x -x2x = 2 ÷2 ÷ 2 x = 1

ProcedureMathematical Procedure
(Algorithm)
2x + 1 = 5
1. Three negative x’s and two units are same as 52. Subtract two units from each side of the equation3. Divide both sides of the equation into two equal groups4. Flip both sides of the equation to make them opposites5. One x is equal to one negative unit
-x -x x – 3 = 2
