2 (x - 3) = 2
2x - 6 = 2
2x = 2 + 6
2x = 8
x = 8 / 2
x = 4
So, your final answer is 4
Hope this helps!
Answer:
22500
Step-by-step explanation:
Just go back 4 from were the decimal point is and when you run out of numbers add a zero
Mean = sum of all values ÷ total number of values
∴ mean = (27+32+14+19+24+26+22+32+29) ÷ 9
mean = 25
1/10 = 0.1 meters per second.
Then just divide 5 by 0.1 and you get 50 seconds.

System of Linear Equations entered :
[1] x + 2y = 5
[2] x - y = 4
Graphic Representation of the Equations :
2y + x = 5 y + x = 4
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = y + 4
// Plug this in for variable x in equation [1]
[1] (y +4) + 2y = 5
[1] 3y = 1
// Solve equation [1] for the variable y
[1] 3y = 1
[1] y = 1/3
// By now we know this much :
x = y+4
y = 1/3
// Use the y value to solve for x
x = (1/3)+4 = 13/3
Solution :
{x,y} = {13/3,1/3}
