Answer:

x=1 , y=0

Step-by-step explanation:

2x+y=2.......1

x+1=y+2

x-y=2-1

x-y=1...... 2

from equation 2 we get ,

x-y=1

x=1+y

putting the value of x in equation 1 we get,

2*(1+y) +y=2

2+2y+y=2

2+3y=2

3y=2-2

3y=0

y=0/3

y=0

putting the value of y in equation 2 we get,

x-0=1

x=1+0

x=1

hence x=1 , y=0

\\ \sf\longmapsto 2x+y=2

\\ \sf\longmapsto 2x=2-y

\\ \sf\longmapsto x=\dfrac{2-y}{2}\dots(1)

And

\\ \sf\longmapsto x+1=y+2

\\ \sf\longmapsto x=y+2-1

\\ \sf\longmapsto x=y+1

  • Put the value

\\ \sf\longmapsto \dfrac{2-y}{2}=y+1

\\ \sf\longmapsto 2-y=2(y+1)

\\ \sf\longmapsto 2-y=2y+2

\\ \sf\longmapsto 2-2=2y+y

\\ \sf\longmapsto 3y=0

\\ \sf\longmapsto y=\dfrac{0}{3}

\\ \sf\longmapsto y=\infty

  • Put in eq(1)

\\ \sf\longmapsto x=\dfrac{2-y}{2}

\\ \sf\longmapsto x=\dfrac{2-\infty}{2}

\\ \sf\longmapsto x=\dfrac{2}{2}

\\ \sf\longmapsto x=1

PLEASE HELP, ITS URGENT I WILL GIVE BRAINLY...
Liono4ka [1.6K]

Answer:

Cost of the box of pencils = x = $4

Cost of the notebook = x+2 = 4+2 = $6

Cost of package of pens = 3x = 3(4) = $12

Step-by-step explanation:

Let the cost of the box of pencils = x

Cost of the notebook = 2 more than the pencils cost = x+2

Cost of package of pens = 3 times the pencils cost = 3x

The total was $22, so we can say:

(x)+(x+2)+(3x) = 22

5x=22-2

x=20/5

x=$4

Cost of the box of pencils = x = $4

Cost of the notebook = x+2 = 4+2 = $6

Cost of package of pens = 3x = 3(4) = $12

What is the value of the missing angle?a, 720b, 120c, 128d, 138
Zigmanuir [339]
The sum of all the interior angles in a hexagon is 720°, so if you add up all the angles and then take them away from 720, you'll get your answer:
152 + 85 = 237
237 + 85 = 322
322 + 125 = 447
447 + 135 = 582
So 720 - 582 = 138°, which is your answer. I hope this helps!

30 fortyths into a decimal​
lana [24]

Answer:

0.3

Step-by-step explanation:

Percent means 'per 100'. So, 30% means 30 per 100 or simply 30/100. If you divide 30 by 100, you get 0.3 (a decimal number). So, to convert from percent to decimal, simply divide by 100 and remove the '%' sign. There is a easy way to convert from percent to decimal: Just move the decimal point 2 places to the left.

Hope this helps :)

pls give brainliest :p

And let me know what you think of my pfp :0
