Answer 2

1.

$2c + 3c = 310 \\ 5c = 310 \\ c = 62$

2.

$25y - 18y = 168 \\ 7y = 168 \\ y = 24$

Answer 3

a. 2c + 3c = 310

Combine like terms on the left side of the equation:

2c + 3c = 5c

Now, you have:

5c = 310

To solve for c, divide both sides of the equation by 5:

5c/5 = 310/5

c = 62

So, the solution to the equation is c = 62.

b. 25y - 18y = 168

Combine like terms on the left side of the equation:

25y - 18y = 7y

Now, you have:

7y = 168

To solve for y, divide both sides of the equation by 7:

7y/7 = 168/7

y = 24

So, the solution to the equation is y = 24.
