1000 + 50x = 500 + 75x
First move 500 by subtracting it from 1000.
500 + 50x = 75x
Now subtract 50x from 75x.
500 = 25x
Then divide 500 by 25.
20 = x
They would've saved the same amount($2,000) on the 20th week.
Isolate the variable by dividing each side by factors that don't contain the variable.
x > 6
The rules of exponents tell you that you can distribute the exponent to each of the factors. When one already has an exponent, those exponents multiply.
Answer:
The value of x is
.
Step-by-step explanation:
Given expression is:

We have to solve this for x.
First we will multiply both sides of the equation by 3

2(x-2) = 12x
2x-4=12x
Now we will be subtracting 2x from both sides of the equation
2x-2x-4=12x-2x
-4=10x
10x=-4
Dividing both sides by 10

Hence,
The value of x is
.
I think isn't anyone of these alternatives because if we put number 15 in the place of y it is x-y=30. X-15=30
X=30+15=45.
X=45
