X=7
But to show your work you would put
-1x=7
Then divide -1x by -1 and 7 by -1 to cancel it out, and you get x=8
The greatest common factor would be 4 since when you take 2 from both, you are left with 14 and 24 in which you can still take 2 from.
400=220(1.03)^t
1.8181=1.03^t
ln 1.8181=ln 1.03^t=t ln 1.03
ln 1.8181/ln 1.03=t
t=20.225 years

2x+y=5
y+3=2x
y+3-3 = 2x-3
y= 2x -3
2x + y =5
2x + 2x -3 = 5
Answer:
ONE: x = 10
Step-by-step explanation:
3x + 6 = -1 - 3 + 4x
3x + 6 = -4 + 4x |subtract 6 from both sides
3x = -10 + 4x |subtract 4x from both sides
-x = -10 |change the signs
x = 10
