Here is an equation 2x + 9 = -15. What are three different equations that have the same solution as that equation? Show or explain how you found them Please

Equations with the same solutions are equivalent equations.

The equivalent equations are: , and

The equation is given as:

Multiply through by 2

Add 5 to both sides of

Collect like terms at:

Hence, the equivalent equations are: , and

To find those equations we can do any multiplication or division of both sides of the equation:

Examples:

2x + 9 = -15              | · 2

4x + 18 = -30

2x + 9 = -15              | · (-1)

-2x - 9 = 15

2x + 9 = -15               | ÷ 2

x + 4.5 = -7.5

There is the same solution: x = -12.

you need to show us the graph.

step-by-step explanation:

domain is all the x values included in the

0 ≤ x ≤ 2

range is all the y values of the graph

-2 ≤ y ≤ 2

***keep in mind that there are different ways to show domain and range

hope this !
