Answer:
x=-7/9
y = 12/9
Step-by-step explanation:
6x + 2y = -2
3x - 2y = -5
9x = -7 (-2y and +2y eliminated)
x = -7/9
if 3x -2y = -5 then
3 ×(-7/9) -2y =-5➡
-21/9 -2y = -5➡
-2y = -5 + 21/9
-2y = -24/9
Answer: 9x=-7
Line up the 2 equations like when you add( one on top of the other)
6x+2y=-2
3x-2y=-5
Your going to add the number from the top and add the number directly below it
That would give you
6x+3x = 9x
2y + (-2y)=0 do not put 0 just leave it blank
they cancel each other out since the number is the same but one is negative and the other is positive
-2 + -5=-7
Finally bring put the answers you got together in the corresponding order according to the equation and bring down the equal sign
Final answer:
9x=-7
The sales tax depends on which state you live in. For example, in Texas, the sales tax is 8.14%. Therefore the game would be $59.47.
x= 30/7
See image below:)
(2x + y)(2x - y)
1. Simplify the square 4x²:
(2x)² - y²
2. Apple the difference of two squares formula <em>x² - y² = (x + y)(x - y)</em>:
hope this helps!
5a+8 /a+b is the answer.
