Simplifying
5(6.2a + 9.8) = 18
Reorder the terms:
5(9.8 + 6.2a) = 18
(9.8 * 5 + 6.2a * 5) = 18
(49 + 31a) = 18
Solving
49 + 31a = 18
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-49' to each side of the equation.
49 + -49 + 31a = 18 + -49
Combine like terms: 49 + -49 = 0
0 + 31a = 18 + -49
31a = 18 + -49
Combine like terms: 18 + -49 = -31
31a = -31
Divide each side by '31'.
a = -1
Simplifying
a = -1
