-7x + 6x + 8 = x - 10<br> Solve for x pls

Art [367]

-x + 8 = x - 10
8 - x = x - 10
8 = x - 10 + x
8 = 2x - 10
8 + 10 = 2x
18 = 2x
18/2 = x
9 = x
x = 9

Solve the simultaneous equations. You must show all your working to find x and y. 1/2x -3y = 9 5x y + y = 28

dedylja [7]

Answer:

$\huge\boxed{x = 6 , y = -2}$

Step-by-step explanation:

$\sf \frac{1}{2} x - 3y = 9-----------(1)\\5x + y = 28 ----------(2)$

Taking equation (1)

$\sf \frac{1}{2} x -3 y=9$

Multiplying both sides by 2

$\sf x-6y = 18$

Adding 6y to both sides

$\sf x = 18+6y$

Putting this in (2)

5(18+6y) + y = 28

90 + 30y+y = 28

31y+90-28 = 0

31 y + 62 = 0

31y = -62

Dividing both sides by 31

y = -2

Now,

x = 18 + 6y

x = 18+6(-2)

x = 18-12

x = 6

Find the 11th partial sum of the summation of negative 7i plus 22, from i equals 1 to infinity.

marta [7]

I think you mean,

$\sum_{i=1}^{\infty}(7i+22)$

You can use the usual formula,

$S_{k}=\frac{k}{2}(a_1+a_k)$

That in this case is,

$S_{11}=\frac{11}{2}(29+99)=704$

Where I have used,

$a_k=7\cdot k +22$
