2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
y = 4, x = 6
Y=4-(2x/3)
-2x plus 3y equals 1
2x + 3y = 12 y = -2/3 y + 4 slope is -2/3
x=12 y=4
2x + 3y = 12 x = 1.45, so 2 * 1.45 + 3y = 12 2.9 + 3y = 12 3y = 12 - 2.9 = 9.1 y = 9.1/3 = 3.0333... or 91/30 or 3 1/30.
If: 2x-3y = -15 and x = 4y Then: x = -12 and y = -3
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
y = 4, x = 6
2x/3y
Y=4-(2x/3)
-2x plus 3y equals 1
2x-3y=13
2x - 3y = 6 2x = 6 + 3y 2x - 6 = 3y : 3y = 2x - 6 y = 2/3x - 2
x = 3 and y = 2 (3,2)
