In Middle School math, it means to find out what number ' x ' must be in order for the equation to be a true statement. In middle school, it can only be one number.

Step-by-step explanation: Solving an equation means finding the value of the variable that makes the equation true.

Let's look at an example.

Solve the following equation.

3x + 1 = 7

To solve the equation, we need to get <em>x</em> by itself on one side and we do that by subtracting 1 from both sides to get 3x = 6. Now just divide both sides of the equation by 2 and we find that <em>x = +2</em>.

Thus, the solution to the equation is x = +2.

So the value of the variable is +2.

A certain hybrid car has a mileage rating of 57 miles per gallon. if the car makes a trip of 293 miles, how many gallons of gaso
dlinn [17]
To determine the number of gallons of gasoline that is used, we need to know the rate of usage of gasoline. This rate would describe the number of gasoline in units of volume that is being used per distance in units of length. In this case, we need the rate in units of miles per gallon. From what is asked and the given values, we simply divide the rate to the the total distance that was traveled by the car. We calculate as follows:

Gallons of gasoline = 293 miles / 57 miles / gallon
Gallons of gasoline = 5.14 gallons

Therefore, about 5 gallons of gasoline was consumed by the hybrid car for a distance of 57 miles.
