6.2(a+b)+2.6(a+b)+3a=

Solution for 6.2(a+b)+2.6(a+b)+3a= equation:

Simplifying
6.2(a + b) + 2.6(a + b) + 3a = 0
(a * 6.2 + b * 6.2) + 2.6(a + b) + 3a = 0
(6.2a + 6.2b) + 2.6(a + b) + 3a = 0
6.2a + 6.2b + (a * 2.6 + b * 2.6) + 3a = 0
6.2a + 6.2b + (2.6a + 2.6b) + 3a = 0

Reorder the terms:
6.2a + 2.6a + 3a + 6.2b + 2.6b = 0

Combine like terms: 6.2a + 2.6a = 8.8a
8.8a + 3a + 6.2b + 2.6b = 0

Combine like terms: 8.8a + 3a = 11.8a
11.8a + 6.2b + 2.6b = 0

Combine like terms: 6.2b + 2.6b = 8.8b
11.8a + 8.8b = 0

Solving
11.8a + 8.8b = 0

Solving for variable 'a'.

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

Add '-8.8b' to each side of the equation.
11.8a + 8.8b + -8.8b = 0 + -8.8b

Combine like terms: 8.8b + -8.8b = 0.0
11.8a + 0.0 = 0 + -8.8b
11.8a = 0 + -8.8b
Remove the zero:
11.8a = -8.8b

Divide each side by '11.8'.
a = -0.7457627119b

Simplifying
a = -0.7457627119b
