Answer:
2, 15
Step-by-step explanation:
LCM= Lowest Common Denominator
4, 30 divided by 2 is the lowest because you cant do 3 because ti wouldn't work for (4) and it wouldn't be 4 because it would make 30 into 7.5 which is not right
so the answer is 2, 15
Answer:
the answer would be (-4,1)
Answer:
x =1.28571428571
Step-by-step explanation:
6x + 2y = -10
y = -4x - 8
6x + 2(4x - 8) = -10
6x + 8x - 8 = -10
14x - 8 = 10
(we put together the like terms)
14x = 10 + 8
14x = 18
x = ![\frac{18}{14}](https://tex.z-dn.net/?f=%5Cfrac%7B18%7D%7B14%7D)
x = 1.28571428571
Answer:
no solutions
Step-by-step explanation:
3x - 6y= -12
x - 2y= -8
Solve the second equation for x
x-2y=-8
Add 2y to each side
x-2y+2y = -8+2y
x = -8+2y
Substitute this into the first equation every place to see x
3x-6y=-12
3(-8+2y) -6y=-12
Distribute the 3
-24 +6y -6y =-12
-24 = -12
Since this is never true there are no solutions.
