x=2y-1
2y+26 = 28 2y = 28-26 2y = 2 y = 1
(1, 1)
x = 3 and y = 2
Both of them are equations!The solution is (x, y) = (2, 1).
x=2y-1
(3, 2)
2y+26 = 28 2y = 28-26 2y = 2 y = 1
(1, 1)
x = 3 and y = 2
The slope of the line of 2x plus 2y equals 7 is (7/2x - 1).
Both of them are equations!The solution is (x, y) = (2, 1).
3x+2y = 1 2y = -3x+1 y = -1.5x+0.5
y = -1
