Answer 1

picture 1 answer : no solution

picture 2 answer : Z= 30

picture 3 answer : X= 6

picture 4 answer : no solution

picture 5 answer : Y= -19

Answer 2

Picture #1:

x/6 + 3 = x/6

cancel x/6

the answer is?no solution

Picture #2

multiply both sides by 5

(6(5 - z))/5 = -z

6(5-z) = -5z

30 - 6z = -5z

30 = z or z = 30

Picture #3

0.7x - 3.9 = .3

0.7x = 4.2

x = 6

Picture #5

multiply by 3 both sides

7 + 10y = 9y - 12

y + 7 = -12

y = -19

Picture #4

6x + 12 + 6 = 2x + 16 + 4x

6x + 18 = 6x + 16

cancel 6x

answer: NO solution
