Kevo’sEquations
 

Hello, and welcome to Kevo’s equations. Here you will learn to accurately solve for one variable, solve literal equations, and how to write an equation from a given point on a line and it’s slope.

Good Luck!
 



 

This is how to start out solving equations.


-5x = 10-15
Since the equation has like terms subtract 15 from 10
-5x = -5
Then you have –5x = -5
-5x = -5

-5      -5
To get x by itself divide both sides of the equation by -5
x = 1
Thus the answer x = 1

 


 

Congratulations,

The wise man is very proud of you!!!
 
 

 Let’s try another one!


 
 7x+7 = 2(x+1)  Use the distributive property on the right side of the problem
 7x+7 = 2x+2  Now you have an equation to work with!
 7x+7= 2x+2
-2x      -2x		  Now, subtract 2x from both sides.
 5x+7 = 2  Now get x by itself.
5x+7 = 2
     -7   -7		 Now subtract 7 from both sides of the equation.
5x = -5 Now you know what to do!!!
5x = -5
5       5		 Use division to get x by itself
x = -1 You finished the problem!!!


Warp speed ahead to the next problem!
 

  Let’s try doing a literal equation!



 

E = mc² Solve for c (speed of light)
E = c²

m     m

 Now divide both sides by m!
E = c²

m

 Now try to get c by itself.
sqrt E = sqrt c²

       m

 Take the square root of both sides to get c by itself.
c = sqrt E

             m

 Great Job !!!

 

Let’s HOP on over to the next problem!
 

Now give an equation for the line. Put in Slope-Intercept form.

Hint (mx+b)


 
With slope = 3 through point (2, 9)
You already have the slope and all you have to find is the y-intercept.
y-intercept (0, 3)
Find the y-intercept
y = 3x+3
Now just plug in the slope and the y-intercept in the equation, and you are done.

You did very well!!

Smile!!!
