Solve the following systems of equations: 4x+5y=-4 4x+3y=12 X=? 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)
