x = 5

Step-by-step explanation:

The given expression is -2(x + 6) + 3 = -11x + 4(x + 4)

Now we have to solve this expression to evaluate the value of x.

-(2x + 12) + 3 = -11x + 4x + 16

-2x - 12 + 3 = - 11x + 4x + 16

-2x + ( -12 + 3) = (-11x + 4x) + 16

-2x - 9 = - 7x + 16

-2x - 9 + 7x = 16

5x - 9 = 16

5x = 16 +  9

5x = 25

x =

x = 5

Therefore, x = 5 is the answer.

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!

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
