I hope you got your answer

Answer 2

Answer:

Step-by-step explanation:

1)    7(x -4) + 13 = 6

7x -28 + 13 = 6

7x - 15 = 6

7x = 15 + 6

7x =21

x =21/7

x = 3.

2)    6(5x-2)+12=30

30x-12+12=30

30x=30

x=1

3)  36=9+3(4t+1)

36=9+12t+3

36=12+12t

36-12=12t

24= 12t

24/12=t

2=t

4) 2x - 2 = x+2

2x-x = 2+2

x = 4

5)   5y - 2 = 3y +6

5y-3y = 6+2

2y = 8

y= 8/2

y=4

6)  9x = 18*5/5

9x = 18

x = 2

7)  2b/3 = 3+5

2b/3 = 8

2b = 8*3

2b = 24

b = 12

8)  3t = 2*2/3

3t = 4/3

t = 3*4/3

t = 4

9)  x/8 = 5-2

x/8 = 3

x = 3*8

x = 24

10)  a/5 = 2-3

a/5 = -1

a = -1*5

a = -5
