4x=3x+1 => (4x-3x)=1 => x=1 therefore the value of x is 1.

-4x + 4y = 1
The answer to the problem of 13 equals -4x plus 9 is x equals -1.
5x+1
x = -½
If you subtract 4x on each side, you get 5 = -1, which is false. Note that this doesn't depend on the value of x, so this is false for any value of x.
If: 3x+5 = 4x+1 Then: x = 4
x-intercept of y equals -4x plus 4 y = -4x + 4 0 = -4x + 4 -4 = -4x 1 = x So 1 is the x-intercept
SWAQ
16x2 + 8x + 1 = 0 : This factorises to (4x + 1)(4x + 1) = 0 When 4x + 1 = 0 then 4x = -1 : x = -1/4.
