X-2y=300 and 6x-y-95 =0 find solution of elimination method​

Mathematics

Tasya [4]3 years ago

There are 2 ways to do this with elimination method. You can either multiply the first equation by 6 or the second equation by 2. I think multiplying by 2 is easier therefore that's the way I'm going to show you.

x-2y=3001️⃣

6x-y-95=0 -simplify> 6x-y=952️⃣

multiply both sides of second equation by 2 to make 2y and eliminate

2️⃣*2

12x-2y=1903️⃣

Now we can eliminate!

3️⃣-1️⃣

12x-2y-(x-2y)=190-300

11x=-110

x=-10

Now substitute this back into either of the equations.

-10-2y=300

2y=-10-300

y=-155

So we get answers

x=-10

y=-155

Now check our work:

-10- 2*-155=-10+310=300 Correct!

6*-10- -155-95=155-95-60=60-60=0 Correct!

I really hope this helped you and if you have any more question about a step in how I got the answer, you can always ask in the comments and I will come answer whenever I see it!

The length of a field in yards is a function f(n) of the length n in feet. Write a function rule for th
lara [203]

Answer:

f(n) =  \frac{n}{3}

Step-by-step explanation:

Recall that:

3ft = 1 \: yd

This implies that:

6ft = 2yds

9ft = 3yds

In general:

n \: ft =  \frac{n}{3}  \:  \: yds

We can therefore write the function rule:

f(n) =  \frac{n}{3}

What’s the expression for “seven times x is no more than 15”
Andru [333]
The answer is 7x≤15 because 7 times x (7x) can't be greater than 15, so the inequality would be less than or equal to because it had to be less than or equal to 15.

A truck that can carry no more than 6600 lb is being used to transport refrigerators and upright pianos. Each refrigerator weigh
gayaneshka [121]

250x + 525x = 6,600

250(11) + 525(6) = 6,600

2750 + 3150 = 6,600

5,900 = 6,600

So in conclusion, 11 refrigerators and 6 pianos will not overload the truck.

Hope this helped!
