Group our variables a and 5a subtract 5a from both sides a + 8 - 5a = 5a - 5a
Cancel 5a on the right side:
-4a + 8 = 0
Group constants
Group our constants 8 and 0. subtract 8 from both sides -4a + 8 - 8 = 0 - 8
Cancel 8 on the left side:
-4a = -8
Divide each side of the equation by -4
-4a
-4
=
-8
-4
a = 2
Final Answer
a = 2
What is the Answer?
a = 2
