Answer:
x=1/14 and y=1/12
Step-by-step explanation:
7x+5y+12+7x+7y=14
⇒14x+12y=2
and set x and y in 0
then you will have 14*(1/7)=2 and 12*(1*6)=2
and you want somthing that makes x + y =2
so you sett 14*x=1 and 12*y=1
that is if i did noy misunderstanding the question
Answer:
x=-1
y=-3
Step-by-step explanation:
3x-2y=3(1)
5.(1) <=> 15x-10y=15 (2)
15x-4y=-3 (3)
(2)-(3) <=> -6y=18
Answer:
1 solution
Step-by-step explanation:
x^2 - 14x + 49 = 0
Factor the expression:
x - 7
------------------------
x | x^2 | - 7x |
- ------------------------
7 | - 7x | 49 |
------------------------
(x - 7)^2 = 0
x - 7 = 0
x = 7
Answer:
5
Step-by-step explanation:
8x - 6 > 12 + 2x
Subtract 2x from each
8x -2x -6 > 12+2x-2x
6x -6 > 12
Add 6 to each side
6x -6+6 > 12+6
6x > 18
Divide by 6
6x/6 > 18/6
x > 3
The only value greater than 3 is 5
12.25 inches. the equation to find that would be 3.5 squared or 3.5 times 3.5
