What is 4x-2y=8 and y=2x+1 using substitution

Mathematics
1 answer:
Setler [38]3 years ago
8 0

Answer:

No Solution

Step-by-step explanation:

4x-2y=8

y=2x+1

Make the first equation into where it says y=.

-2y=-4x+8

y=2x-4

Substitute either equation into the other as y=.

2x+1=2x-4   or    2x-4=2x+1

Switch terms around so they're with their like terms. Make sure it becomes the opposite when switching.

2x-2x=-1-4    or    2x-2x=4+1

0=-5                     0=5

Since x did not come back to equal an answer, this problem is not workable. There is no solution to it. If you were to do it a different way, there still would not be a solution to it.

78 divided by 190 <br><br>steps
Goryan [66]
78 x 100 = 7800 

<span>How many times does 190 go into 780? </span>
<span>≈ 4....190 x 4 = 760 </span>

<span>780 - 760 = 20...bring down the extra 0 to make it 200. </span>

<span>How many times does 190 go into 200? </span>
<span>≈ 1...subtract 190 from 200 to get a remainder of 10 </span>

<span>190 ÷ 7800 ≈ 41</span>

Hope I Helped You!!! :-)

find the geometric mean of 10 and 18. if the answer is not a whole number leave it in the simplest radical form
Galina-37 [17]
a_{1} =10 \ and = a_{2} =18 \\ \\ Geometric \ is : \\ \\ a=\sqrt{a_{1}\cdot a_{2}} \\ \\a=\sqrt{10\cdot 18} =\sqrt{180} =\sqrt{36\cdot 5}=\sqrt{36}\sqrt{5}=6\sqrt{5} \approx 6 \cdot 2.24 \approx 13.44
