2. ) 8a = 2a+30 ________________
3. ) 39c-78 = 33c ________________
4. ) X + 15-6 =12 ________________
5. ) 35-b = 25 ________________​

Answer 1

1. )

5n = 2n + 6

-2n -2n

3n = 6

/3 /3

n = 2

2. )

8a = 2a + 30

-2a -2a

6a = 30

/6 /6

a = 5

3. )

39c - 78 = 33c

-39c -39c

-78 = -6c

/-6 /-6

13 = c

4. )

x + 15 - 6 = 12

x + 9 = 12

-9 -9

x = 3

5. )

35 - b = 25

-35 -35

-1b = -10

/-1 /-1

b = 10
