You can always add or subtract
same value to/from both sides of equation. The same is true about multiplication and division.
In your case you have to subtract
x from both sides of equation in order to get rid of it on the left side:


But it's easier to remember that if you want to move some member of equation to other side, you just have to
change it's sign. Let's practice a bit using your equation (I have added "plus" signs where they are usually omitted to better understend what's going on):

Move
2y to the right side:

Move
8 to the left side:

Move both
x and
2y to the right side:
10 mean 100%
x mean 7%
--------------------
x=7*10/100 = 70/100 = 0,7

Answer:
9
Step-by-step explanation:
1) order all numbers least to greatest:
3,5,9,17,20
cross of a number on the right side and do the same on the left until u have 1 number left
u will be left with 9
9 is ur median
hope this helps!
54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=
Answer:
x= 0
Step-by-step explanation:
Let's form an equation using the slope of the line.

☆ (x₁, y₁) is the 1st coordinate and (x₂, y₂) is the 2nd coordinate
Let the gradient of line be m.


The product of the gradients of 2 perpendicular lines is -1.
m(⅓)= -1

m= -1 ×3
m= -3




x= -1 +1
x= 0
