HELP PLEASE HELP ME

B) (80, 120)

Step-by-step explanation:

Since we are given the equations, let's start with finding y.

x + y = 200 and x = y - 40, therefore we can plug in the x into the first equation

(y - 40) + y = 200 (add 40 to both sides and add the two ys)

2y = 240 (divide by 2)

y = 120

So from here, we know it's either B or C. Now for x, plug y back into the original equation, then prove it with the second.

x + 120 = 200 (subtract 120 from both sides)

x = 80

Then try with the second

80 = 120 - 40 (which checks out!!)

In conclusion, y = 120 and x = 80, so your answer is B.

Hope that helps!
