Simplifying

15a + 7b = 0

Solving

15a + 7b = 0

Solving for variable 'a'.

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

Add '-7b' to each side of the equation.

15a + 7b + -7b = 0 + -7b

Combine like terms: 7b + -7b = 0

15a + 0 = 0 + -7b

15a = 0 + -7b

Remove the zero:

15a = -7b

Divide each side by '15'.

a = -0.4666666667b

Simplifying

a = -0.4666666667b
