Question 1210543
.
USE THE SUBSTITUTION METHOD TO SOLVE a-2b=a, 2a+3b=4
~~~~~~~~~~~~~~~~~~~~~~~~


<pre>
Your starting equations are

     a - 2b = a,    (1)

    2a + 3b = 4.    (2)


In equation (1), cancel the identical terms 'a' in both sides.


You will get  -2b = 0,  which tells you that  b = 0.


Substitute b= 0 into equation (2)

    2a + 3*0 = 4,

    2a       = 4

     a       = 4/2 = 2.


<U>ANSWER</U>.  a = 2, b = 0.


You may check it on your own that (a,b) = (2,0) satisfies the given equations.

At this point, the problem is solved completely.
We found the unique solution to the given system of equations.
