Answer:
x = 0
Step-by-step explanation:
First we need to move either 5r or 2r to the other side, in order to isolate the variable.
We'll move 5r, in this case, by subtracting it from 2r. Now we got: -11 - 3x = -6 - 5.
Next we subtract 5 from -6 to get
-11 - 3x = -11.
Now we can add 11 on both sides to get -3x = 0.
Finally divide by -3 to get x = 0.
Hope this helps :)
Answer:
Convert fractions into decimal, round up if the decimal is 0.5 and/or higher, and round down if less than 0.5
Example for question 1: 5/6= 0.83 ← greater than 0.5, so round up to 2
Step-by-step explanation:
1. 2
2. 5
3. 113
4.86
5. 66
6. 19
7. 72
Add 2x and subtract 7
5 -2x +2x < 7 +2x . . . . . . showing 2x added
5 < 7 +2x . . . . . . . . . . . .. simplified
5 -7 < 7 -7 +2x . . . . . . . . showing 7 subtracted
-2 < 2x . . . . . . . . . . . . . . . simplified
Now, divide by 2
-1 < x
The solution is -1 < x.
