Y=x-5 y=7 solve for x simplify your answer as much as possible

Mathematics
1 answer:
love history [14]2 years ago
5 0

Answer:

x = 12

Step-by-step explanation:

First of all, what you will want to do is plug in your y into the first equation, to find the x.

y = x - 5 ----> 7 = x - 5

Next, think about your possible solutions here.... Flip the equation:

5 + 7 = ? ---> 5 + 7 = 12

Now, plug both your x and y in the original equation:

7 = 12 - 5  Does this match?

7 = 7          Yes!

This is the simplest way I can explain it! I hope it is understandable, correct, and helpful. Have a great day :D

tensa zangetsu [6.8K]

Answer:

First: 15

Second: 21

Third: 45

Step-by-step explanation:

In order to create the equation we need to represent the evenings with an alebraic term, in thsi case we are going to represent the second evening with an X

Second evening:x

The first night she got 6 fewer calls than the second: Second-6=x-6

The third night she received 3 times the first: 3(first night)=3(x-6)

The equation is First Night plus second night plus third night equals 81.

First+second+third=81\\x+(x-7)+3(x-6)=81\\x+x-7+3x-18=81\\5x=81+21+6\\5x=105\\x=\frac{105}{5} \\x=21

So the first evening he received 15 calls, the second he received 21 and the third one he received 45.
