Answer:
One solution. (x,y) = (-5,25)
Step-by-step explanation:
y = -5x
x + y = 20
x + (-5x) = 20
-4x = 20
x = -5
y = -5 (-5)
y = 25
Answer:
not enough
Step-by-step explanation:
only given 2 congruent sides and you need 3
It’s a left side 8’5 right????
After solving the equation we get y=2 when x = 15
Step-by-step explanation:
We need to complete the solution of the equation 
We need to find value of y when x equals -15
For finding value of y, we will put value of x= -15 in the given equation:



Adding -15 on both sides


Divide both sides by -8

So, After solving the equation we get y=2 when x = 15
