It can also be written as 3x + 7. The value of the expression will depend on the value of x.
3x=81 3x/3=81/3x=27
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
IF 3X-1=11, WHAT IS THE VALUE OF X 2 + X?
Do you mean "what is the value of x when 3x - 2x = 15?" in that case, the value of x is 15
It has no value but if you mean: y = 3x+5 then it is a straight line equation that can be plotted on the Cartesian plane
