Answer:
x= 1
Step-by-step explanation:
The value of y = -5x
Plug it in the equation of y + 4x = -1
So it becomes, -5x + 4x = -1
Combine like terms which are -5x and 4x which equals to -x
Eliminate the negative sign because x cannot be negative. Apply that to -1. It becomes 1.

Answer:
Step-by-step explanation:
Equation 1: y = -5x
Equation 2: y + 4x = -1
Step 1. Substitute y in equation 2 using equation 1
You would get, -5x + 4x = -1
Step 2. Combine like terms
-x = -1
Step 3. Cross out the negatives
x = 1
Step 4. Substitute x in Equation 1 to get y
y = -5(1)
y = -5
Hope this helps :)
Have a great day!
