Question

(5a + 3b + 4c) * (5a+3b+4c)

Answer 1

Answer:

Simplifying

5a + 3b = 4c

Solving

5a + 3b = 4c

Solving for variable 'a'.

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

Add '-3b' to each side of the equation.

5a + 3b + -3b = -3b + 4c

Combine like terms: 3b + -3b = 0

5a + 0 = -3b + 4c

5a = -3b + 4c

Divide each side by '5'.

a = -0.6b + 0.8c

Simplifying

a = -0.6b + 0.8c
