Answer:
x=-6
Step-by-step explanation:
2x+y=-4
5x+3y=-6
solve :
multiply first equation by 3
6x+3y=-12
5x+3y=-6
subtract the two equations : 6x+3y-5x-3y=-12-(-6)
x=-12+6
x=-6
Answer: False
Nothing is 100% certain no matter how sure it seems. This is especially true with statistics. There's always going to be some amount of error. The goal is to minimize the error as much as possible in the best cost-effective manner.

In improper its- 81/10
Hope this helps :D
The answer to that would be 0.0098.
Answer:
G = -4x - 4
x = -1
Step-by-step explanation:
step 1: flip your equation and turn G into zero
ex: -4x - 4 = 0
step 2: add 4 to both sides
ex: -4x - 4 + 4 = 0 + 4 (-4x = 4)
step 3: divide both sides by -4
ex: -4x/-4 = 4/-4 (x = -1)
step 4: plug -1 into x then solve to check your answer
ex: -4(-1) - 4 = 0
4 - 4 = 0
0 = 0 (when this says 0 = 0 then that means your answer is always true)
