Mean equals average
So 8 plus 10 equals 18
18 divided by 2 is 9
Mean is 9
To solve for x, you need to isolate/get the variable "x" by itself in the equation:
3x - 3(x + 1) = 3 Distribute/multiply -3 into (x + 1)
3x + (-3)x + (-3)1 = 3
3x - 3x + 1 = 3
1 = 3
Your answer is no solution because the variable "x" is canceled out and 1 ≠ 3
Answer:
Step-by-step explanation:
s(1-30/100)=420
s(100-30)/100=420
s(70/100)=420
s(7/10)=420
7s=4200
s=600
This is as far as I could get X=-94+m<2
Answer:
it's true! it's easier to solve for y because there's no coefficient in front of it unlike the second one that has "9y."
