Answer:

1. x = -7

2. n = 9

3. x = -2

Step-by-step explanation:

5x + 3 = -32

    -3      -3

5x = - 35

÷ 5    ÷ 5

x = -7

__________________________________________________________

4 + [tex]\frac{n}{3}[/tex] = 7

-4       -4

[tex]\frac{n}{3}[/tex]   =    3

× 3  × 3

n = 9

__________________________________________________________

x - 4/ 3 = -2

( x  − 4  )  ⋅  2  =  3  ⋅  (  x  -  2  )

2x - 8 = 3x - 6

-2x        -2x

-8 = x - 6

+ 6     +6

-2 = x

Hope this helped!

Answer:

1: -7  2: 9  3: -2

Step-by-step explanation:

First Equation. (You first want to isolate the variable)

5x + 3 = -32  (subtract 3)

    -3       -3

5x = - 35  (divide by five)

x  = - 7

Second Equation. (Isolate variable)

4 + n/3 = 7 (subtract four by each side to get rid of it on the variable's side)

-4           -4

n/3 = 3 (isolate n, so mutiple each slide by 3)    

n = 9

Third Equation. (isolate again)

x-4/3 = -2 (mutiple  each side by three to get rid of the three on variables side)

x-4 = -6 (add four to each side to cancel out four on the variables side)

x=-2

hope this helps!
