1 x 279, 3 x 93, 9 x 31
3x=18 x=18/3 x=6
If 3x - 9 = -6 then 3x must equal 3. Therefore x = 1 !
X= -2 ! Since the equation must equal zero - 17+3x must equal 11. The variable 3x HAS to equal -6... therefore x is equal to minus 2.
It is equal to 21x You can not find x.
x + x + 1 + x + 2 = 279 3x + 3 = 279 3x = 279 - 3 = 276 x = 92 Hence the three consecutive numbers are 92, 93, and 94
3x^2
2x minus 3x is equal to -x.
1 x 279, 3 x 93, 9 x 31
3x = 7-5x 8x=7 x = 7/8 x = 0.875
3x=18 x=18/3 x=6
2x minus 3x is equal to -x.
If 3x - 9 = -6 then 3x must equal 3. Therefore x = 1 !
X= -2 ! Since the equation must equal zero - 17+3x must equal 11. The variable 3x HAS to equal -6... therefore x is equal to minus 2.
It is equal to 21x You can not find x.
You need an equal sign to solve for x.
3x = x+8 so 3x-x = 8 hence 2x = 8 and so x = 4
