solving equations involving Rational numbers???????

Question

I don't understand this at all, so when you answer, answer STEP by STEP. p.s. / means divide

3a+ 1 / 5=2

/ is NOT a fraction, it means DIVIDE!!!!!!

Answer 1

Will take a guess and say that question is:-
(3a + 1) / 5 = 2
3a + 1 = 10
3a = 9
a = 3

Answer 2

First off, rational numbers are numbers that can be converted to fractions. 0.2, which equals1/5, is a rational number. 3.14159 is NOT a rational number.

So let's solve this equation step-by step.

3a+ 1 / 5=2

First, subtract 1/5 from both sides.

3a + 1/5 = 2
becomes
3a = 2-1/5

2 is the same as 10/5. So...

3a=10/5 - 1/5

3a = 9/5

Now, we divide both sides by 3 to isolate the variable, a.

3a = 9/5
becomes
a = 3/5

There you go.
