False the Pythagorean theorem is A2+B2=C2 hope this helps!
Because you are not adding the x's .When you add the coefficients, the variable comes along with it.
Answer:
X = -2
y = 2
Step-by-step explanation:
Substitute y=x + 4 in the second equation to find x
x+4 = 2x + 6
subtract x from both sides
4 = x + 6
subtract 6 from both sides
-2 = x
put -2 in for x in the first equation
y= 2
