X and Y stand for the x and y of an ordered pair.
You could plug in the coordinate for x.
In the equation 3x plus 7 equals 13, x is equal to 2.
None because without an equal sign it's not an equation
X= -2 ! Since the equation must equal zero - 17+3x must equal 11. The variable 3x HAS to equal -6... therefore x is equal to minus 2.
No, an equation needs an "=".
Ten. That means 3x equals 30, and 30 divided by three is ten.
an equation
3x + 2y = 8 This is an equation. It could be the equation of a line.
(-3,-4)
I think you mean (3x ± 1)^2 = (3x+1)(3x-1)?
50, 53, 59
To solve the equation 6x plus 4-3x,first subtract 3x from 4 which leaves you with 1x. The equation now reads 6x plus 1x, which equals 7x. --- Actually, to simplify this, we have to keep the numbers multiplied with the variables from the plain numbers. The equation based on the question it this: 6X + 4 - 3X So there is a +6X a -3x and a +4. So we simplify by consolidating the numbers multiplied with the Xs. So 6X - 3X is 3X. So we have 3x + 4. There is no way to solve this since we have only part of it and no equal sign.
If this is algebra then; 3x plus 12x = 15x
