Answer: Division of Equality
Step-by-step explanation: In this equation, using division, we can find what y is by dividing 5 on both sides. Y equals to 15.
Natural numbers, also known as counting numbers
When she decided to combine the 5x and 2x she would have been subtracting the 2x leaving her with 3x-2=7which is 3x=9, x=3
Answer:


The equations have the same slope but different y-intercepts. This means the lines are parallel and there is no solution (since they do not intersect).
Question:
What is 3(x + 2) - 2(x + 1)?
Steps:
When you solve this type of equation always use the distributive property formula to solve this equation!
Formula: a(b + c) = ab + ac
So, what is 3(x + 2) ?
Also, what is -2(x + 1)?
Then, put it back into the equation for you to solve this problem.
So, this would be the new equation:
3x + 6 - 2x - 2
Then, what you want to do is put variables next to each other and the numbers next to each other so it will be easier to simplify:
3x - 2x + 6 - 2
Then, simplify:
x + 4 is the answer!
Since 3x - 2x = x and 6 - 2 = 4
Hope that helped!!
