Hw set 1/ directions: solve each equ
1. ) 4x + 27 = 3x

x = -27

Step-by-step explanation:

4x+27=3x

Subtract 3x from both sides of the equation.

==> 4x + 27 -3x = 3x - 3x

==> 4x - 3x + 27 = 0

==> 1x + 27 = 0

Subtract 27 from both sides,

==> x + 27 - 27 = 0 - 27

==> x = -27

1 1/5

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!
