Answer:
(7, 10.5)
Step-by-step explanation:
just going to use substitution here.
so you would substitute the y value in the equation x-2y=-14 with 2x-3.5.
it should look like: x-2(2x-3.5)=-14
solve the equation and you get x=7.
plug in 7 for x in either equation and you get y= 10.5.
Answer:
2(3x+2y) and 6x+4y
Step-by-step explanation:
If we expand all of the solutions and the expression we are trying to match, we can see which expression has all matching terms.
The expression we are matching to can be expanded to:
2(2x+4y+x-2y)
4x+8y+2x-4y
6x+4y
Solution 1: NO
2(x+5y) and 2x+12y
2x+10y and 2x + 12y
Solution 2: NO
2(x+2y) and 2x+4y
2x+4y and 2x+4y
Solution 3: YES
2(3x+2y) and 6x+4y
6x+4y and 6x+4y
Solution 4: NO
2(3x+6y) and 6x+12y
6x+12y and 6x+12y
The correct should be X=10
Ugh i’m sorry i hate the links don’t press on them they steal ur info. also i’m really sorry i don’t know the answer i’m just trying to help out!
Answer:
x=2 and x=-5
Step-by-step explanation:
factoring the equation
x^2+6x-4-3x-6=0
x^2+3x-10=0
(x-2)(x+5)=0
x=2 and x=-5
