2X + 7 = 8 and 2-4 / 3x = 4 are solved by the properties of the equation and tested


1: 2X + 7 = 8 test: 2x0.5 + 7 = 8
Solution 2x + 7-7 = 8-7
x=0.5
2: 3x = 4 test: 4 out of 3x3 = 4
X = 4.3
X = 4 / 3



0.5-0.2x = 0.9 use the properties of the equation to solve the equation


First shift the term: - 0.2x = 0.9-0.5, then simplify - 0.2x = 0.4, and then divide both sides by - 0.2 to get x = - 2
