Question

What is 8t+3r-7t-9r simplified

Answer 1

Answer:

t-6r

Step-by-step explanation:

8t+3r-7t-9r

you subtract 7t from 8t to get

1t, or just t, and now you are left with

t+3r-9r

so then if you add 3r to negative 9r, you get -6r, so now you have

t+(-6r)

but always remember if the equasion goes x+(-y) you can just change the plus sign into a minus sign to get x-y, or in this case,

t-6r

Answer 2

Answer:

t-6r

Step-by-step explanation:

8t+3r-7t-9r

8t-7t=t

3r-9r=-6r

∴ 8t+3r-7t-9r simplified is t-6r
