Answer:
x = 20
Step-by-step explanation:
3x + 26 = 2(3 + 2x)
~Simplify
3x + 26 = 6 + 4x
~Subtract 26 to both sides
3x = -20 + 4x
~Subtract 4x to both sides
-x = -20
~Divide -1 to both sides
x = 20

Answer:
12 pound
Step-by-step explanation:
Let 
be the weight of the package.
For Lone Star Shipping, the cost will be:
For Discount Shipping Company, the cost will be:
We hence equate these two expressions equal to each other, since the cost should be same.
The first thing we must do for this case is to define a variable:
x: number of years
y: total salary
We have then:
For first company:
y = 1500x + 31000
For second company:
y = 2000x + 28500
Equaling both equations we have:
1500x + 31000 = 2000x + 28500
Clearing x:
2000x - 1500x = 31000 - 28500
500x = 2500
x = 2500/500
x = 5
Answer:
It will take for the salaries to be the same about:
x = 5 years
