1/2(2+a)=3a+4/3 solve it
Mumz [18]
1/2(2+a)=3a+4/3

first, you use the distributive property<span>

</span>then your problem changes to...

1 + 1/2a = 3a + 4/3

then you subtract 1/2a with 3a

1  = 2 1/2a +4/3
<span>
now you subtract 1 with 4/3
</span>
-1/3 = 2 1/2a

now you divide -1/3 with 2 1/2a 

-2/15 = a

A = -2/15 is your answer. Hope this helps :)
