Yes.
3X = 9 ( equation means set as an equality )
In words; three times the variable X is equal to nine.
To solve just divide both sides by 3.
3X = 9
X = 3
So, you are saying;
3(3) = 9
and this is proof in the mathematical sense of the statement/equation.
3x-6y=9 -3x -3x -6y=9-3x __ ____ -6 -6 y=9-3x ____ -6
3x+3=30 X=9
The answer has been right under your nose all this time.The equation of y equals -3x isy = -3x
your equation is y=3x + 4 here are five parallel equations... y=3x + 5 y=3x + 6 y=3x + 7 y=3x + 8 y=3x + 9
3x-4y = 9 -4y = -3x+9 y = 3/4x-9/4 The equation parallel to this can be y = 3/4x+9/4 because the slope or gradient is the same but the y intercept is different.

-6
It is a linear equation in one variable, x.
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
It is a straight line equation that can be simplified to: y = 3x-9
3x - 24 = 3Add 24 to each side of the equation:3x = 27Divide each side by 3 :x = 9
3x + 2y = 8 This is an equation. It could be the equation of a line.
