Answer:
What is exactly the question?
This is very confusing what are you trying to figure out give a little more information and I will be more than happy to hell you
So what we do is we first get the x on the right side: 7x-x = 6x.
Now we get the 5 to the left side: 71-5= 66.
Now our equation is 66=6x.
We divide 66 by 6 which makes x=11
Answer:
21 & 11
Step-by-step explanation:
Let x = first number and y = second number. We need to find the values of x and y, so we need to set up a system of linear equations. The first equation would be x + y = 32 because x and y add up to 32. Then the second equation would be x - y = 10 to represent that the two numbers have a difference of 10. Solving by elimination, we add and get 2x = 42, so x = 21. Then substitute 21 for x in either one of the equations to get y = 11.
Answer:
2y² + 14y - 15
Step-by-step explanation:
(2y² + 8y - 9) - (- 6y + 6)
Remove first parenthesis and distribute second by - 1
= 2y² + 8y - 9 + 6y - 6 ← collect like terms
= 2y² + 14y - 15
