First of all you have to make them equal to each other. What I mean is the following
3x+20=2x+40
Then you should just solve for x
#2 because it’s a Pythagorean theorem triple

Answer:
x = 1 y = -4
Step-by-step explanation:
- Plug the value of y into the other equation.
x + 3y = -11
x + 3(-4x) = -11
x - 12x = -11
-11x = -11
x = 1
- Now substitute the value of x into any equation.
y = -4x
y = -4(1)
y = -4
