I just need the answer to 5c - 3 (a + 3a)

5c - 3 (4a)

Step-by-step explanation:

If you're just grouping and adding them together you would get 5c - 3 (4a).

Answer:Simplifying

a = 1 + 0.3333333333b + 1.666666667c

Step-by-step explanation:

Simplifying

3a + - 1b + - 5c = 3

Solving

3a + - 1b + - 5c = 3

Solving for variable 'a'.

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

Add 'b' to each side of the equation.

3a + - 1b + b + - 5c = 3 + b

Combine like terms: - 1b + b = 0

3a + 0 + - 5c = 3 + b

3a + - 5c = 3 + b

Add '5c' to each side of the equation.

3a + - 5c + 5c = 3 + b + 5c

Combine like terms: - 5c + 5c = 0

3a + 0 = 3 + b + 5c

3a = 3 + b + 5c

Divide each side by '3'.

a = 1 + 0.3333333333b + 1.666666667c

Simplifying

a = 1 + 0.3333333333b + 1.666666667c
