Answer:
x = 4.5
Step-by-step explanation:
The way you can figure this out is first, minus both sides by -5x to get ride of the extra x
3x - 5x = 5x - 5x -9
-2x = -9
Then make sure that the -2x is positive cause you can't have a neagtive variable.
-2x times -1 = -9 times -1
2x = 9
Then divded both sides by 2 to get the answer
2x/2 = 9/2
x = 4.5
Hope this helps and have a great day
Answer: x = 4.5
Step-by-step explanation:
1) Reorder the terms:
3x = -9 + 5x
2) Solving
3x = -9 + 5x
3) Solving for variable 'x'.
4) Move all terms containing x to the left, all other terms to the right.
5) Add '-5x' to each side of the equation.
3x + -5x = -9 + 5x + -5x
6) Combine like terms: 3x + -5x = -2x
-2x = -9 + 5x + -5x
7) Combine like terms: 5x + -5x = 0
-2x = -9 + 0
-2x = -9
8) Divide each side by '-2'.
x = 4.5
9) Simplifying
x = 4.5

The answer is y=0. As you can see in the graph when x=1, y=0. I added a picture so you can see it.
Answer:
1st one is 30,
2nd one is 20,
so the 3rd one will be 30+20 so the answer is 50
Step-by-step explanation:
Answer revealed in the attachment below.
(x^1/2 y^-2/3)^-6
= x^(1/2*-6) y^[(-2/3) *(-6)]
= x^-3 y ^4
= y^4 / x^3
answer is D. y^4 / x^3
We know that y=7x, so we just need tu put it into the 1st equation
So we found x. Now we can find y
Answer:
x=1, y=7; or (1;7)
