Question

8th pre-algebra Only do number 22! Worth 10 points please help

Answer 1

x = 4

Explanation:

First, you have to find 10 + 1.5x = 4x. You want to subtract the lowest coefficient that has a variable of x, in this case it's 1.5x. When you do this you have to do it to both sides of the equal sign. When you do this, you are left with 10 = 2.5x. The whole point in solving equations is to get 'x' on one side of the equal sign alone. So you have to divide next. Since 2.5 is the coefficient of x, you divide by 2.5. Whatever, you do to one side you do to the other. So divide the other side by 2.5. When done you get x = 4. Therefore, 4 is when they are equal to each other.

Answer 2

after 5 movie rentals

Explanation:

find 10+1.5x=4x. then using the subtraction property of equality you subtract 1.5x from both sides to get 10=2.5x. you then use the division property of equality to divide both sides by 2.5. you get x=4 so 4 is when they are equal to each other. then add one to that so it is skewed in favor of one side.
