Find the sum of (8a + 2b - 4 ) and ( 3b - 5 )
please help !!!

Step-by-step explanation: (8a + 2b + -4) = (3b + -5)

Reorder the terms:

(-4 + 8a + 2b) = (3b + -5)

Remove parenthesis around (-4 + 8a + 2b)

-4 + 8a + 2b = (3b + -5)

Reorder the terms:

-4 + 8a + 2b = (-5 + 3b)

Remove parenthesis around (-5 + 3b)

-4 + 8a + 2b = -5 + 3b

Solving

-4 + 8a + 2b = -5 + 3b

Solving for variable 'a'.

Move all terms containing a to the left, all other terms to the right.

Add '4' to each side of the equation.

-4 + 8a + 4 + 2b = -5 + 4 + 3b

Reorder the terms:

-4 + 4 + 8a + 2b = -5 + 4 + 3b

Combine like terms: -4 + 4 = 0

0 + 8a + 2b = -5 + 4 + 3b

8a + 2b = -5 + 4 + 3b

Combine like terms: -5 + 4 = -1

8a + 2b = -1 + 3b

Add '-2b' to each side of the equation.

8a + 2b + -2b = -1 + 3b + -2b

Combine like terms: 2b + -2b = 0

8a + 0 = -1 + 3b + -2b

8a = -1 + 3b + -2b

Combine like terms: 3b + -2b = 1b

8a = -1 + 1b

Divide each side by '8'.

a = -0.125 + 0.125b

Simplifying

a = -0.125 + 0.125b

ok one would be money, and the other would be refreshments or something similar. if each bag of popcorn is 5.00 and each drink is half of that that means drinks are 2.50 the proper way to do that would to look and see how much of each you can buy without exceeding a limit of 30.00
