Question

If you have a problem that has multiple variables, you can solve it using a
system of equations. Think of a real-world example where you would need
to solve using a system of equations. Write two or three sentences
describing your example. Include the equations in your description, but do
not solve the system. That will be left to your classmates. helppppp

Answer 1

Step-by-step explanation:

two times of a number added to 18 gives 70

what is value of X.

2x + 18 = 70

2x = 52

X = 26 is answer

can u talk to me in comment section

Answer 2

The system of equations representing the described condition will be $x+y=15\;and \;2x+4y=40$.

A variety of problems can be solved using the system of equations.

Consider a simple problem of purchasing notebooks and pens from the market.

You bought some pens at $2 per pen and some notebooks at $4 per notebook from the market. At the end of shopping, you have spent $40 and you got 15 objects in your bag.

Write the given situation in the form of equations.

Let x be the number of pens bought and y be the number of notebooks bought.

So, the equations can be made as,

$x+y=15\\2x+4y=40$

Therefore, the system of equations representing the described condition will be $x+y=15\;and \;2x+4y=40$.
