Respuesta :
y = -5
5x + 4y = -20
5x + 4y = -20
5x + 4(-5) = -20
5x - 20 = -20
+ 20 + 20
5x = 0
5 5
x = 0
(x, y) = (0, -5)
5x + 4y = -20
5x + 4y = -20
5x + 4(-5) = -20
5x - 20 = -20
+ 20 + 20
5x = 0
5 5
x = 0
(x, y) = (0, -5)
Y=-5
5x+4y=-20
Substitute y into the equation.
5x + 4(-5) = -20
5x + -20 = -20
+20 +20
5x = 0
x = 0
Now we have our values.
Answer: y = -5 and x = 0
5x+4y=-20
Substitute y into the equation.
5x + 4(-5) = -20
5x + -20 = -20
+20 +20
5x = 0
x = 0
Now we have our values.
Answer: y = -5 and x = 0
