By first subtraction b and then dividing by m, the solution of the linear equation for x is:
(y - b)/m = x
<h3>How to solve the linear equation for x?</h3>
Here we have a linear equation that defines the variable y in terms of the variable x:
y = m*x + b
Where m and b are real numbers.
Now we want to find x in terms of the variable y, this means that we need to isolate the variable x.
if first we subtract b in both sides, we get:
y - b = m*x + b - b
y - b = m*x
If now we divide both sides by m, we get:
(y - b)/m = m*x/m
(y - b)/m = x
This is the linear equation solved for x.

Answer: x=20/3=6.67
Step-by-step explanation:
To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.
-----------------------------------------------------------------------------
Given
x:10=9:6
Cross Multiply
9·x=6·10
9x=60
Divide 9 on both sides
9x/9=60/9
x=20/3=6.67
Hope this helps!! :)

Answer:
12.5 hours
Step-by-step explanation:
budget: 200
fix cost: 50
hourly rate: 12
hours: ?
----
First we deduct the fix 50 dollars cost from the total budget.
Then we divide the remaining amount with the hourly rate
( 200 - 50 ) / 12 = ?
? = 12.5 hours
