There can be no answer.
y = y is an identity - a statement that is true for all values of y.
That leaves y = - 3 - x. It is not possible to solve one linear equation in two unknown variables (x and y). You can only rearrange the equation: for example, to x+y+3=0.
3x - y = 4 Get y by itself to see if it is the same as y = 3x - 4: 3x = 4 + y 3x - 4 = y Therefore, 3x - y = 4 is the equivalent of y = 3x - 4.
y = 3x = 12y = 12
y = 15 (by transitivity)
-9
3x-y=9 y=3x-9
y = 3x 3x + 4y = 30 3x + 4(3x) = 30 3x + 12x = 30 15x = 30 x = 2 y = 3x y = 3(2) y = 6 (2, 6)
Their graphs are.
y = 3x + 1 y = 3x + 2 y = 3x + 3 y = 3x
3x - y = 12 is the same as 3x - 12 = y, or y = 3x - 12.
Slope=3, y-intercept=0. y=3x or y=3x+0
y = 3x + 1
y = 3X - 1
