Answer 2

Let's solve each of these equations step by step:

1. 2x + 4 = 6

   Subtract 4 from both sides: 2x = 6 - 4 2x = 2

   Now, divide both sides by 2 to solve for x: 2x/2 = 2/2 x = 1

So, x = 1.

2. 6c - 12 = 30

   Add 12 to both sides: 6c = 30 + 12 6c = 42

   Now, divide both sides by 6 to solve for c: 6c/6 = 42/6 c = 7

So, c = 7.

3. 26 - 4a = 48 - 15a

   Let's first get all the terms with 'a' on one side: 26 + 15a - 4a = 48

   Combine like terms: 26 + 11a = 48

   Now, subtract 26 from both sides: 11a = 48 - 26 11a = 22

   Finally, divide both sides by 11 to solve for a: 11a/11 = 22/11 a = 2

So, a = 2.

4. 23y + 30 = 80 - 2y

   Let's get all the terms with 'y' on one side: 23y + 2y = 80 - 30

   Combine like terms: 25y = 50

   Now, divide both sides by 25 to solve for y: 25y/25 = 50/25 y = 2

So, y = 2.

5. 15x - 6 = 24

   Add 6 to both sides: 15x = 24 + 6 15x = 30

   Now, divide both sides by 15 to solve for x: 15x/15 = 30/15 x = 2

So, x = 2.

6. 32b - 29 = 35

   Add 29 to both sides: 32b = 35 + 29 32b = 64

   Now, divide both sides by 32 to solve for b: 32b/32 = 64/32 b = 2

So, b = 2.

7. 40t - 8 = 55 + 19t

   Let's get all the terms with 't' on one side: 40t - 19t = 55 + 8

   Combine like terms: 21t = 63

   Now, divide both sides by 21 to solve for t: 21t/21 = 63/21 t = 3

So, t = 3.
