Yes.
Any equation in which y is some ratio of x plus some offset is linear. In this case, it is a line with a slope of 2, which intersects the y axis at point (0, 1), and the x axis at (-0.5, 0).
y = 2x + 1 IS a linear equation!
x=1
x = 0
-2x plus 3y equals 1
Yes it is, since it can be represented in the form y = mx + b
x=5.54x+1= 2x+12-1 -14x=2x+11-2x -2x2x=11/2 /2x=5.5
NM equals 2x + 1, as stated in the question!
Y = 2x + 1
The answer to 1 over 2x plus 13 equals 9 is x equals -8.
Subtracting y = x + 1 from y = 2x - 1 gives 0 = x - 2; whence, x = 2, which is your answer.
The solution is (x, y, z) = (2.5, 1, 2.5).
x equals 4
