Answer: x = 20
Step-by-step explanation:
1) Move all terms to the left:
x-13-(x/2-3)=0
2) Get rid of parentheses
x-x/2+3-13=0
3) Multiply all the terms by the denominator
x*2-x+3*2-13*2=0
4) Add all the numbers together, and all the variables
-1x+x*2-20=0
5) Multiply elements
-1x+2x-20=0
6) Add all the numbers together, and all the variables
x-20=0
7) Move all terms containing x to the left, all other terms to the right
x=20
Hope This Helps (From My Notes)
For inverse variation, y = k/x
From the given, 9 = k/8
k = 9 * 8 = 72
Thus, y = 72/x
Therefore, when x = 32, y = 72/32 = 2.25
y = 2.25
Answer:
Step-by-step explanation:o
x + y = 10........(1)
x - y = 14..........(2)
Adding (1) and (2)
2x = 24
x = 24/2
x = 12
And x + y = 10.......(1)
12 + y = 10
y = 10 - 12
y = -2
The number are 12 and -2
Answer:
