Answer 1

Answer:

x=-8 y=8

Step-by-step explanation:

2x+3y=8--> 1

4x+5y=8-->2

Multiply 2 in first equation

2(2x+3y=8)

4x+6y=16-->3

Subtract second equation from third equation

4x+6y=16

(-) 4x+5y=8

_________

y=8-->4

_________

Substitute fourth equation in first equation

2x+3(8)=8

2x+24=8

2x= -16

x= -16/2

x= -8
