Solve the following systems of equations:<br> 4x+5y=-4<br> 4x+3y=12<br><br> X=?<br> Y=?
Mrac [35]

For this case we have the following system of equations:

4x + 5y = -4\\4x + 3y = 12

We multiply the second equation by -1:

-4x-3y = -12

We add the equations:

4x-4x + 5y-3y = -4-12\\5y-3y = -4-12\\2y = -16\\y = \frac {-16} {2}\\y = -8

We find the value of "x":

4x = 12-3y\\x = \frac {12-3y} {4}\\x = \frac {12-3 (-8)} {4}\\x = \frac {12 + 24} {4}\\x = \frac {36} {4}\\x = 9

Thus, the solution of the system is given by:

(x, y) :( 9, -8)

ANswer:

(9, -8)
