-x + 7 = 27
Subtract 7 from both sides: -x = 20 or x = -20
Because that is how negative numbers are defined.
(-3) - (-7) = (-3) + (+7) = (-3) + 7 = 4
3x + 6 = 27.Subtract 6 from both sides: 3x = 27 - 6 = 21.Divide both sides by 3: x = 21/3 = 7.x = 7
- 3.5 plus 10.5 equals 7 is one possible answer.
A negative... as in (-5) + (-7) = (-12). A negative timesa negative is a positive... as in (-5) X (-7) = (+35)
