Answer:

x = [tex]-\frac{41}{19}[/tex]

y = [tex]\frac{7}{19}[/tex]

Step-by-step explanation:

2x = 10y - 8

3x + 4y + 5 = 0

2x = 10y - 8

x = 5y - 4

3x + 4y + 5 = 0

3 ( 5y - 4 ) + 4y + 5 = 0

19y - 7 = 0

19y = 7

y = [tex]\frac{7}{19}[/tex]

x = 5y - 4

x = 5 ( [tex]\frac{7}{19}[/tex] ) - 4

x = [tex]-\frac{41}{19}[/tex]
