Answer:
x = 0.462
Step-by-step explanation:
215x = 99.3
x = 99.3/215
x = 0.462
Answer:
ok
Step-by-step explanation:
Answer: A. (4,1)
Step-by-step explanation:
2x -5y = 3
x -3y = 1
Change the equation to isolate a variable so you can substitute it in the other one.
x = 1+3y so
2(1+3y) -5y = 3
2 + 6y -5y =3
2 + y = 3
y=1
Back to the easy equation we isolated
x = 1+3(1)
x= 4
(4,1) is a point where x=4 and y=1
