You are searching for the value of r.
-7r + 6 = 9 - 6r + 1
Notice the 9 and the 1 on the right side. Since they are common factors (terms not attached to x), they can be added.
-7r + 6 = -6r + 10
Subtract 6 from both sides to eliminate the 6 on the left.
-7r = -6r + 4
Add 7r to both sides, leaving r-terms on only one side.
0 = r + 4
Subtract 4 from both sides, so one side is constant and the other is the variable.
-4 = r
The answer is -4 is equal to r.
9r-1?
(r + 1)(2r + 5)
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
1 plus 1 equals one fact
This appears to be a number trick or joke. The answer is that 1 hour, plus 1 minute, plus 59 minutes, will equal 2 hours.
I think so.r2 + 7r + 6 = [ (r+6) (r+1) ]
9r-1?
(r + 1)(2r + 5)
No...it equals 4...
1 plus 1 plus 1 plus 1 equals 1 times 4. 1 times 4 equals 4. 4 minus 4 equals 0. 0
4+1=5. Plus 4 equals 9. Plus 77685769844446473 equals 77685769844446482. Plus 3 equals 77685769844446485. Plus 8 equals 77685769844446493. Plus 1 equals 77685769844446494. Plus 9870998342523322424 equals 1064785604097768918. Plus 4 equals 1064785604097768922.
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.

1 plus 1 equals one fact
3 plus 1 plus 4 equals 8
This appears to be a number trick or joke. The answer is that 1 hour, plus 1 minute, plus 59 minutes, will equal 2 hours.
1 plus 1 equals 1 (in Boolean logic) 1 plus 1 equals 10 (in base 2)
