Answer:
a = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
To solve for a, you must isolate it (variables on one side, constants on the other):
8 = 3a + 4 (starting equation)
8 - 4 = 3a + 4 - 4 (subtract 4 from both sides)
4 = 3a + 0 (calculate)
4 = 3a (no need to write +0)
[tex]\frac{4}{3}[/tex] = [tex]\frac{3a}{3}[/tex] (divide both sides by 3)
[tex]\frac{4}{3}[/tex] = a (simplify -- 3/3 = 1)
So, a = [tex]\frac{4}{3}[/tex].
