Answer 1

Answer:

(-9,-2)

x= -9

y= -2

Step-by-step explanation:

x+5y=-19

x-5y=1

solve the equation

x+5y=-19

x=1+5y

substitute the value of x into an equation

1+5y+5y=-19

add 5y to 5y

1+10y=-19

subtract 1 to -19

10y=-20

divide both sides by 10

y= -2

substitute the value of y into an equation

x=1+5•(-2)

multiply 5 to -2

1+-10

add 1 to -10 but since 10 is a negative the equation is subtraction.

x= -9

(-9,-2)
