2x+2y
6x-2x-6xy-2x-2y4x-2y=2x-2y-14xy
10x - 5y + 2x - 3y = 12x - 8y
If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines
3x-2y+9+9y-x = 2x+7y+9
2x+2y
4x + 2y = -8 → 2y = -4x - 8 → y = -2x - 4
-2x=2y+5 +2x -2y -2y=2x+5 /-2 y=-1/1+2.5
6x-2y
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
X + ( 2Y - 2X - Y ) is equal to Y - X
The answer is -5x + 2y. The terms with the same variable are combined by adding or subtracting their coefficients, and then the result is written with the corresponding variable. In this case, -3x and -2x combine to give -5x, and 4y and -2y combine to give 2y.
the answer to this problem is -2x^2y^2
It is an expression of terms that can be simplified to: x+2y+2
-4(7x-3y-z)-(-6)(9x-z+2)
3x + 5 + x + 10 + 2y 4x + 2y + 15 |:2 2x + y + 7.5 2x + y + 7.5 is equivalent to the original.
-2x + 2y = 4 is equivalent to twice -2 + y = 2 which is the equation of a straight line.
