Geometry @Nicoley269

Answer 1

Okay they are both the same length

Answer 2

Meaning that they both have to be 12.5

Answer 3

\(3y-x=12.5\\
2x-y=12.5\)

Answer 4

Do you understand?

Answer 5

Ok

Answer 6

So from here we can isolate y from
\(3y-x=12.5\)

Do you know how to do that?

Answer 7

No

Answer 8

(first, add x on both sides)

Answer 9

Ok

Answer 10

3y=12.5+x

Answer 11

Right and now divide by 3 on both sides

Answer 12

Y=4.16666.... +1/3x

Answer 13

Right you can leave it as a fraction but decimal is fine too
Substitute it into the second equation
\(2x-(\frac{12.5}{3}+\frac13x)=12.5\)

Distribute and solve for x

Answer 14

Yes, now subtract 2x and 1/3x

Answer 15

5/3x-12.5/3=12.5

Answer 16

\(\frac53x-\frac{12.5}{3}=25\)

Right so now add \(\frac{12.5}{3}\) and 25

Answer 17

ok... im not rly good with fractions

Answer 18

Get them to the same base (multiply 25 by 3)
\(\large \frac{12.5}{3}+\frac{75}{3}\)
That should help

Answer 19

ok o i would get 87.5/3

Answer 20

\(\frac53x=\frac{87.5}{3}\)
Now we isolate x, we should get

x=10

Answer 21

ok so we just plug it in. right?

Answer 22

I have to go rn but

From here we can just substitute back into either equation

Isolate y and we should get y=7.5

x= 10
y=7.5

\(3(7.5)-10=12.5\\
22.5-10=12.5\)\(\checkmark\)

Answer 23

ok

Answer 24

thank you
