3y + 1 = 22 what’s the equation

Step-by-step explanation:

Hi there! I'm glad I was able to help you!

To solve for the temporarily unknown variable requires two steps, but I'll break them down for you so that it's easier to understand.

STEP 1: Subtract 1 from both sides of the equation. We do this so that we aren't left with any unknown numbers on either side. This makes it harder for us to solve for the unknown variable with the +1 being there.

Now we are left with our equation that looks like this:

The +1 on the left side of the equation has been canceled, but the rule we use in math states that whatever we do to one side of the equation must be done to the other, to keep things even.

STEP 2: Divide both sides of the equation by 3. Yay, more canceling!

Like we did before, we do this so we aren't left with any "stray" numbers on either side of the equation. This cancels out the 3's on the left side of the equation, leaving us with just our variable, y.

Our final answer is correct, but just in case you want to double check it so you're 100% certain, all you have to do is replace the variable in the equation by our new answer, and check and see if it's a true statement.

I hope this helped you! Leave a comment below if I can assist with anything else! I'd love to help! :)

answer-

a. the total cost of a taxi ride includes an initial charge of approximately $3.30

solution-

in the graph,

x axis represents the distance traveled and

y axis represents the total fare

the best fit line intersects the y axis approximately at 3.30 or y-intercept is 3.30. at x=0, i.e when the taxi is still, the value of y or the cost of the fare is 3.30. that means $3.30 is the fixed charge which will be levied along with the other fare.

the slope of the line represent the cost per mile. as the best fit line is straight line, so the price per mile is constant.
