Explain why it is necessary to reverse the inequality symbol when multiplying both sides of an inequality by a negative number. Please make sure you provide an example to support your explanation

The inequality sign changes because you are switching the signs of the values in the inequality. So you must flip the inequality sign as well. [ Once all values become negative, that means that negatives are flipped from one side to the other (or abolished, if both sides were negative). If the sign is not flipped, it makes the solution a whole different range of numbers, because it changes the inequality. ]

7x – 2 = 5x + 10

7x - 5x = 10+2

2x = 12

2x/2 = 12/2

x = 6

7x - 5x = 10+2

2x = 12

2x/2 = 12/2

x = 6

2x + 4 =28

2x = 28 - 4

2x = 24

x = 24/2

x = 12

2x = 28 - 4

2x = 24

x = 24/2

x = 12

17x – 42 = -39

17x = - 39 + 42

17x = 3

x = 3/17

17x = - 39 + 42

17x = 3

x = 3/17

User: Hi can anyone help me because I need to do this in a EZ graph program. I just have to find two points on the line. So we'll choose two values of x, solve for the corresponding values of y, and plot the resulting points (x,y). Here is the math to solve: Y = 4x – 3
**Weegy:** Sorry we can't show you graphs in weegy. (More)
