The common denominator would have to be 42
Answer:
The correct answer is d. (40, 60)
Step-by-step explanation:
To start using the linear combination method, you need a variable that will cancel out. To get this, we will multiply the second equation by -20 and then add together.
x + y = 100
-1.4x - y = -116
-----------------
-0.4x = -16
x = 40
Now that we have the value of x, we plug into one of the original equations to find y.
x + y = 100
40 + y = 100
y = 60
