Question

Solve each of these equations. explain or show your reasoning.

2(x+5)=3x+1


3y-4=6-2y

3(n+2)=9(6-n)

Answer 1

Answer: n = 4

9 = x

y = 2

Explanation:

2 ( x + 5 ) = 3x + 1

2x +10 = 3x + 1

10 = 1x + 1

- 1 -1

9 = 1x

9 = x

3y - 4 = 6 - 2y

5y -4 =6

5y = 10

y = 2

3 (n + 2) = 9 ( 6-n)

3n + 6 = 54 -9n

3n +9n = 54 - 6

12n =54 -6

12n =48

n = 4
