The equation the quantity of x plus 20 over 2 = 3x represents when two tutoring services with different rate plans charge the same fees for a session of x hours. solve for x. x = 10 x = 4 x = −14 x = −17

The value of x is 4 if the equation is (x + 20)/2 = 3x option (B) x = 4 is correct.

What is a linear equation?

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The equation the quantity:

(x + 20)/2 = 3x

The above equation represents when two tutoring services with different rate plans charge the same fees for a session of x hours.

After cross multiplication:

x + 20 = 6x

6x – x = 20

5x = 20

Divide by 20 on both side:

5x/5 = 20/5

x = 4 hours

Thus, the value of x is 4 hours if the equation is (x + 20)/2 = 3x option (B) x = 4 is correct.
