Question 1206950
.
y=5x-13
5x+2y=19
how can I solve this
I couldnt find substition/systems which is what this problem is

<pre>
You have a system of two equations in two unknowns.

First equation expresses y as a linear function of x.
In other words, first equation is just ready to make a substitution.


So, we apply the substitution method and replace y in the second equation
by its expression from first equation.  We get single equation for x then

    5x + 2*(5x-13) = 19.


Simplify and find x

    5x + 10x - 26 = 19

    5x + 10x = 19 + 26

       15x   =    45

         x   =    45/15 = 3.


So, x is just found.

To find y, substitute this value of x into very first equation

    y = 5x - 13 = 5*3-13 = 15-13 = 2.


<U>ANSWER</U>.  The solution is  x= 3, y= 2.
