6x + 7y = -9
-4x - 5y = 5
We can use either substitution or elimination. I prefer substitution so I will explain it that way. You can use elimination as well.
We can solve for x first so we will need to substitute y in terms of x.
6x + 7y = -9
7y = -9 - 6x
y = (-9 - 6x)/7
Plugging this into the other equation:
-4x - 5[(-9 - 6x)/7] = 5
-4x + (45 + 30x)/7 = 5
-28x + 45 + 30x = 35
2x + 45 = 35
2x = - 10
x = -5
Insert this into the other equation to solve for y.
6(-5) + 7y = -9
-30 + 7y = -9
7y = 21
y = 3
Your answer should be (-5, 3). Hope this helps!
Kilograms. Everything else is too high
Here are some solutions: (there are actually an infinite amount of them)
x = 0 , y = 7
x = 1 , y = 8
x = 2 , y = 9
x = 3 , y = 10
x = 4 , y = 11
x = 42 , y = 49
x = pi , y = pi + 7
Answer:
Step-by-step explanation:
Answer:
negative multiples of 3 less than -3
Step-by-step explanation:
if m <9, then
m ={8,7,6,5,4,3,2,1,0,-1,-2,....,..........}
And |6m-55|
So is said that,
when, m= 8
6(8)-55=-6
when, m=7
6(7)-54=-12
when, m = 6
6(6)-54=-18
Since the trend is negative multiples of 3 less than -3
this is my answer
