Answer/Step-by-step explanation:
4(x - 2)= 100 and 2(x - 2) = 50.
We can determine that in both equation x equals 27. But, why is the second one half as much as the first problem? This is because the second problem is being multiplied with a number half as large as the first. Since 27 - 2 = 25 and 25 x 4 = 100 and 25 x 2 = 50 these problems hold up to their function.
If x = 27:
<u>4(x - 2) = 100</u>
27 - 2 = 25
25 x 4 = 100
<u>2(x - 2) = 50</u>
27 - 2 = 25
25 x 2 = 50
Answer:
C
Step-by-step explanation:
If you multiply the top equation by 7, you will get -7x.
Then, if you add -7x to 7x, it will eliminate the x value
