Rewriting this by starting with the negative sign results in
-334 ÷ (212) .
Writing that sign, and then evaluating 334/212 on a calculator, we get:
-1.575 (approximately), which can be rewritten as -1 23/40. This last result is a mixed number in simplified form. Note that -1.575 has been rounded off from a version with 9 decimal places.
A number (we don’t know the number so I’ll use X) plus five. So we can start the equation of with X+5 then divided by 3=7 so X+5➗3=7 so to solve what X is we can just go in reverse. 7 TIMES 3= 21-5=16 so X=16
