Solution for a(-2b+2c)-3a(b+5c)= equation:


Simplifying
a(-2b + 2c) + -3a(b + 5c) = 0
(-2b * a + 2c * a) + -3a(b + 5c) = 0
(-2ab + 2ac) + -3a(b + 5c) = 0
-2ab + 2ac + (b * -3a + 5c * -3a) = 0
-2ab + 2ac + (-3ab + -15ac) = 0

Reorder the terms:
-2ab + -3ab + 2ac + -15ac = 0

Combine like terms: -2ab + -3ab = -5ab
-5ab + 2ac + -15ac = 0

Combine like terms: 2ac + -15ac = -13ac
-5ab + -13ac = 0

Solving
-5ab + -13ac = 0

Solving for variable 'a'.
