solve for each variable pls

Answer 1

Explanation:

1. 3c-7 = 5

3c = 5+7

3c = 12

c = 12/3

c = 4

2. 3z+(-4) = -1

3z -4 = -1

3z = -1 + 4

3z = 3

z = 3/3

z = 1

3. 2v + (-9) = -17

2v -9 = -17

2v = -17 +9

2v = -8

v = -8/2

v = -4

4. 2b-2 = -22

2b = -22 +2

2b = -20

b = -20/2

b = -10

5. 3z +6 = 21

3z = 21 -6

3z = 15

z = 15/3

z = 5

6. -2c -(-2) = -2

-2c +2 = -2

-2c = -2 -2

-2c = -4

c = -4/-2

c= 2

7. 3x -2 = -26

3x = -26 +2

3x = -24

x = 24/3

x = 8

8. -2z -(-9) = 15

-2z +9 = 15

-2z = 15 -9

-2z = 6

z = 6/-2

z = -3

9. -2b +(-8) = -4

-2b -8 = -4

-2b = -4 +8

-2b = 4

b = 4/-2

b = -2

10. 2y +1 = 13

2y = 13 -1

2y = 12

y = 12/2

y = 6

11. 2u -(-9) = 15

2u +9 = 15

2u = 15 -9

2u = 6

u = 6/2

u = 3

12. 2b -5 = 7

2b = 7 +5

2b = 12

b = 12/2

b = 6

13. 3y -5 = -32

3y = -32 +5

3y = -27

y = -27/3

y = -9

14. -2b +(-7) = -7

-2b -7 = -7

-2b = -7 +7

-2b = 0

b = 0/-2

b= 0

15. 3v -(-6) = 6

3v +6 = 6

3v = 6 -6

3v = 0

v = 0/3

v = 0
