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


Simplifying
0 = 5a + -2a(5 + -1b)
0 = 5a + (5 * -2a + -1b * -2a)
0 = 5a + (-10a + 2ab)

Combine like terms: 5a + -10a = -5a
0 = -5a + 2ab

Solving
0 = -5a + 2ab

Solving for variable 'a'.

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

Add '5a' to each side of the equation.
0 + 5a = -5a + 5a + 2ab
Remove the zero:
5a = -5a + 5a + 2ab
