Answer:

1. x = -7

2. n = 9

3. x = -2

Explanation:

5x + 3 = -32

-3 -3

5x = - 35

÷ 5 ÷ 5

x = -7

__________________________________________________________

4 +
(n)/(3) = 7

-4 -4


(n)/(3) = 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

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!
