Answer:

n=4

Step-by-step explanation:

5n+34=-2(1-7n)

1. So first expand.

5n+34=−2+14n

2 Regroup terms.

5n+34=14n−2

3 Subtract 5n from both sides.

34=14n−2−5n

4 Simplify 14n-2-5n to 9n-2.

34=9n−2

5 Add 22 to both sides.

34+2=9n

6 Simplify 34+2 to 36.

36=9n

7 Divide both sides by 9.

36/9=9

8 Simplify 36/9 to 4

4=n

9 Switch sides.

n=4
