Subtract 1/5 on each side to isolate the variable:
a/2=17-1/5--->a/2=16 4/5
Multiply both sides by 2 to further isolate the variable:
a=168/5 or 33 3/5

Okay:
a/2 + 1/5 = 17
Subtract 1/5 from both sides
a/2 = 16 4/5
Multiply both sides by 2
a = 32 8/5 or, 33 3/5

a/2 + 1/5 - 1/5 = 17 - 1/5
a/2 = 84/5
a/2 * 2 = 84/5 * 2
a = 168/5 = 33 3/5
Now do a bunch so you learn it....otherwise you will never pass the exam!

a/2+1/5=17
subtract 1/5 from both sides
a/2=85/5-1/5
multiply both sides by 2
a/2(2)=84/5(2)
a=168/5
a=33.6

a/2 + 1/5 = 17?
Sol'n:
5a+2
----- = 17
10
5a + 2 = 170
5a = 170 - 2
5a = 168
5a/2 = 168/5
a = 33.6

Take it one step at a time. You need to isolate the term with the variable. What do you need to do to both sides of the equation to get a/2 by itself? Then what do you have?
You'll have a/2= something
now - what do you need to do to both sides of the equation to get the a completely by itself? (Hint - you need to multiply both sides by something to cancel out that denominator)

multiply all terms by 10 to get rid of the denominators. Then you should be able to solve easily.
