Answer: x=1,y=0

Step-by-step explanation:

X-2y=1.....equation 1

2x-y=2.....equation 2

X=1+2y.......equation 3

Substitute equation 3into 2

2(1+2y)-y=2

2+4y-y=2

2+3y=2

3y=2-2

3y=0

Y=0/3

Y=0

Substitute for y=0 in equation 1

X-2y=1

X-2(0)=1

X-0=1

X=1

X=1 & Y=0

Is 19-10 equal to20-10 is 19 take away 10 equill to 20 take away 10
Anni [7]
First lets write this out:-
 
            ?
19 - 10 = 20 - 10

Now lets solve:-

19 - 10 =9

   ?
9 = 20 - 10

20 - 10 = 10

9 ≠ 10

Since 9 does not equal 10:-

19 - 10 ≠ 20 - 10

Hope I helped ya!!

Urgent help needed algebra 2

The missing values are shown in the attached picture, and 41 degrees F = 5 degrees C.

<h3>What is unit conversion?</h3>

It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.

We have:

\rm F = \dfrac{9}{5}C + 32

Make subject C and solve:

\rm \dfrac{5}{9}(F-32) = \dfrac{5}{9}\times\dfrac{9}{5}C

\rm \dfrac{5}{9}(F-32) = C

Plug F = 41

\rm \dfrac{5}{9}(41-32) = C

\rm \dfrac{5}{9}(9) = C

41 degrees F = 5 degrees C

Thus, the missing values are shown in the attached picture, and 41 degrees F = 5 degrees C.

Factorize the following expression ab-a-b+1
dolphi86 [110]

Group 'em together

a b − a + 1 − b

a b − a = a ( b − 1 )

Notice that there will be a 1 as without it it'll simply be  ab

1 − b = 1 ( 1 − b )

Notice that it doesn't match with the upper one... so we'll change the signs

1 ( 1 − b ) = − 1 ( b− 1 )

(try to multiply them now!!

Jot them down in one expression

a ( b − 1 ) − 1 ( b − 1 )

You get!!!!!!

( a − 1 ) ( b − 1 )
