Answer:

x= -5

y = -8

Step-by-step explanation:

we have:

-7x-11=-3y         equation 1

-9x+19+8y=0   equation 2

using equation 1 we have:

-7x-11=-3y  

3y - 11 = 7x

x = [tex]\frac{3y-11}{7}[/tex]    equation 3

using equation 3 in equation 2 we have:

[tex]-9(\frac{3y-11}{7}) +19+8y=0[/tex]  

[tex]-9(\frac{3y-11}{7}) +19+8y=0\\\\\frac{-27}{7}y +\frac{99}{7}+19+8y = 0\\\\\frac{29}{7}y +\frac{232}{7} = 0\\\\\frac{29}{7}y = - \frac{232}{7}\\\\y = \frac{-232}{29} \\\\y= -8[/tex]

so we have:

[tex]x = \frac{3*(-8)-11}{7}\\\\x= \frac{-24-11}{7}\\\\x = -5[/tex]
