Solve for x 135+120+ 3X +31+ 4X +15+ 6X -8+ 7X -64+ 5X -4 equals 900

5.0625

Step-by-step explanation:

Step 1:

The given expression can be written as

On solving the above expression

adding all the X terms and constant terms individually

160X + 90 = 900

Step 2:

160X = 810

X = (810/160)  =5.0625

i think it is c, not positive though

step-by-step explanation:

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
