3y - 2 = 13 solve for y
Serhud [2]

Answer:

y = 5

Step-by-step explanation:

3y - 2 = 13

We are solving for y, so we want to isolate it.

Add 2 to both sides.

3y = 15

Continue isolating y by dividing both sides by 3.

y = 5

Check your answer by plugging it back into the original equation.

3y - 2 = 13

3(5) - 2 = 13

Multiply.

15 - 2 = 13

Subtract.

13 = 13

Your answer is correct.

Hope this helps!

Step-by-step explanation:

We are asked to find which value is similar to the value of the expression:

30% of 81.

We know that 30% of 81 could also be represented mathematically as:

30%×81=

which could also be written as:

choice A:

=

Which is not similar to equation (1).
