3x+2y-7=0 2y=-3x+7 y=1/2(-3x+7) or -3/2 x +7/2
x = -2 and y = 3
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
3x + 2y = 7
It equals a simple linear equation in 'y'. Its solution is 7/3 .
x+2y = 7 2y = -x+7 y = -0.5x+3.5
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
3x-2y-7=0
3x = 2y + 7 The standard form is: 3x - 2y - 7 = 0
