If you use the first answer, the equation becomes 2x + 2y = 16. You could subtract this from equation Q to eliminate x.
The second answer makes equation P -2x - 2y = -16. You could add this to equation Q to eliminate x. You can use both of these methods to eliminate the x term, but if you can only choose one, you should choose the second option.
Answer:
x + y = 4
Step-by-step explanation:
Given the 2 equations
3x + 4y = 10 → (1)
2x + 3y = 6 → (2)
Subtract (2) from (1) term by term on both sides
x + y = 4
Answer:
3x+2
Step-by-step explanation:
x+6/x+4+x-3/3
3x+6/4-3/3
3x+6/1/3
3x+6/3
3x+2
V= pi x r^2 x h
V/(pi x h)=r^2
square root of [V/(pixh)]=r
Answer:
Step-by-step explanation:
I translated it into:
60+10x=15x
(x= the amount of months btw)
take 10x from each side
60=5x
divide each side by 5
x=12
one year until the cost of the two is the same.
