Question

Look at the two equations:

-3x + 6 = 21

-3x + 6 <21

Which statement best describes the process used to solve the equations?

Answer 1

From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that the process is exactly the same for solving the equation and solving the inequality

Explanation:

Given that the two equations -3x + 6 = 21 and -3x + 6 <21

To find the statement best describes the process used to solve the equations :

From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that

-3x+6-6=21-6

-3x=15

`x=-(15)/(3)`

∴ x=-5

-3x + 6 <21

-3x+6-6<21-6

-3x<15

`x< -(15)/(3)`

∴ x< -5

From the given equations -3x + 6 = 21 and -3x + 6 <21 we have that the process is exactly the same for solving the equation and solving the inequality.
