It can also be written as 3x + 7. The value of the expression will depend on the value of x.
x = 7
The 7 is contant in 3x + 7, and the 3x term is variable depending on the value of x.
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
x=4
It can also be written as 3x + 7. The value of the expression will depend on the value of x.
x = 7
The 7 is contant in 3x + 7, and the 3x term is variable depending on the value of x.
-3x + 2 = -7 - 2 -2 -3x = -9 so x = 3
x=4
It depends entirely on the value of x.
x = 7
It is an equation and the value of x is 6
X=7
The value of x is -3
It is an equation and the value of x is 7/19
3x2 + 22x + 7 = 3x2 +21x + x + 7 = 3x(x + 7) + (x + 7) = (x + 7)(3x + 1)
