Answer:
11x=1
Step-by-step explanation:
15x+4=5+3x+1x Bring everything with an x in front of it to the left side
15x-3x-1x+4=5 Simplify the x values
11x+4=5 Bring the 4 to the right side
11x=5-4
11x=1
It’s line always goes in both directions

Answer:
Let n represent the number of months after Tina would save the same amount using either option.
400 + 30n = 100 + 50n
400 + 30n − 30n = 100 + 50n − 30n Subtraction Property of Equality
400 = 100 + 20n Combine like terms.
400 − 100=100 + 20n − 100 Subtraction Property of Equality
300 =20n
300
20
=
20n
20
15 months=n
After 15 months, Tina will save the same amount using either option.
400 + 30(15)=100 + 50(15)
400 + 450=100 + 750
850 = 850
After 15 months, Tina will save $850 with either option.

Answer:
16 cars.
Step-by-step explanation:
Let x represent number of sold cars.
We have been that 1st company pays a salary of $8000 plus a commission of $900 for each car sold. We can represent this information in an expression as:

We are also told that second company pays a salary of $14400 plus a commission of $500 for each car sold. We can represent this information in an expression as:

To find the number of cars sold, which will make the total pay the same, we will equate both expressions and solve for x as:






Therefore, 16 cars would need to be sold to make the total pay the same.
