Hello,
Assume v the speed of the eastbound train,
v-14 the speed of the westbound train
v*4+(v-14)*4=800
==>8v=800+56
==>v=107 (mi/h)
Speed of the westbound train: 107-14=93 (mi/h)

The solution set of x^2+12=21
Free_Kalibri [48]

The solution set of the equation is: x = -3, x = 3.

<h3>How to Find the Solutions to an Equation?</h3>

Given the equation, x² + 12 = 21, the solution set is the possible value of x that will make the equation true. To find the values of x, do the following as shown below:

x² + 12 = 21

Subtract 21 from both sides of the equation

x² + 12 - 21 = 21 - 21

x² + 12 - 21 = 0

x² - 9 = 0

Find the difference of the two squares

(x + 3)(x - 3) = 0

x = -3

x = 3

Therefore, the solution set of the equation is: x = -3, x = 3.
