Multiply the first bracket by -4

Multiply the second bracket by 5

(-4)(9r)(-4)(10)

=-36r-40

(5)(10r)+(5)(7)

=-50r+35

-36r-40+50r+35

-36r+50r-40+35 ( rearranging)

Answer:

Step-by-step explanation:

In order for something to have infinite solutions, both sides need to be equal to each other.

Example:

3x + 7y = 7y + 3x

That has infinite solutions

3x + 7y = 7x + 3y

That is not equal to each other because the variables are different.

Hope I helped :)
