Answer:x=8 and y=2

Step-by-step explanation:

To find 2x-4y=8 and 3x+6y=36

Solve simultaneously

Using elimination method

6x-12y=24

6x+12y=72

To eliminate x

-24y=-48

Divide through by -24

y=2

To get x

Substitute for y in equation 1

2x-4(2)=8

2x=8+8

2x=16

Divide through by x

x=8

the third term of an arithmetic sequence is 24 and the fifth is 32 if the first term is a1. which is an equation nth term of the
const2013 [10]
An = a1 + (n - 1)(d)
Where a1 is the first term and d is the common difference.
First find d, the common difference.
24, ____, 32
a3 a4 a5
Subtract 32-24 = 8
Subtract a5 - a3 = 2
Divide 8/2 = 4
d = 4
Use d and one of the values they give us to find a1.
a3 = 24
24 = a1 + (3 - 1)(4)
24 = a1 + 2(4)
24 = a1 + 8
Subtract 8 from both sides
16 = a1
an = 16 + (n - 1)(4)
Can also be written
an = 16 + 4n - 4
an = 4n + 12
