Solve for x in the second equation.

Just add 1 to both sides to get x = 9y + 1

Then plug 9y + 1 into the first equation for x

7(9y+1) - 9y = 1

63y + 7 - 9y = 1

54y + 7 = 1

54y = -6

y = -6/54 or -1/9

Plug y back into one of the equations to get x = 0

Answer: (0, -1/9)

The solution is 0! Because 9x(-1/9)=x-1 which would give you 0

X^- x - 6 and x^ -5x +6 what are thier common factors

Katarina [22]

I guess you mean:

X^2 - X - 6 and X^2 - 5X + 6

X^2 - X - 6 = (X + 2)(X − 3)

X^2 - 5X + 6 = (X − 2)(X − 3)

Based on that, their common factor is:

(X - 3)

The British was able to conquer India because India were not able to?

Marysya12 [62]

Hey there!
India was, and still is now, a third world country.
They <em>could not defend themselves or create a stable government like the one we have today</em>.
They were prone to attack, and the British took the opportunity.
Hope this helps!

Determine if the sequence is arithmetic. If it is, find the common difference. 1) 35, 32, 29, 26, ... 2) −3, −23, −43, −63, ...

1) Yes, it is arithmetic, the common difference is -3. To find this, subtract any number from the number after it.

32 - 35 = -3

2) yes, it is arithmetic, the common difference is -20. To find this, subtract any number from the number after it.

-23 - -3 = -20

3) yes, it is arithmetic, the common difference is -30. To find this, subtract any number from the number after it.

-64 - -34 = -30

4) yes, it is arithmetic, the common difference is -10. To find this, subtract any number from the number after it.

-40 - -30 = -10

yes, it is arithmetic, the common difference is -2. To find this, subtract any number from the number after it.

-9 - -7 = -2

yes, it is arithmetic, the common difference is 5. To find this, subtract any number from the number after it.

14 - 9 = 5

Answer:

Simple Algebra

Step-by-step explanation:

First set the equations equal to each other. Second, combine like terms. You should now have 10 = x. Now substitute the ten for the x and solve.
