can you please help me can you give me example of set in linear equation and how can i solve it?


Sagot :

Linear equations are equations that has one as its highest exponent

example:

1. x + y = 12
2. -6x + y= 6

to solve for x and y 
you can either use elimination or substitution

in this case we use elimination

so we either eliminate x or y
lets eliminate x
 we first multiply 6 on equation 1 and multiply 1 to equation 2 to cancel out x
6(x + y= 6)
1(-6x + y= 6)
it would then be

6x + 6y = 36
+
-6x + y = 6

to cancel out x we add both equations

0x + 7y= 42

so Y=6 

and to find x substitute the value of x on either of the equations
