What would x and y be if the equation is 3x-4y equals 10 and -3x equals 4y equals 8?
3x - 4y = 10-3x - 4y = 8 -> add line 1 to line 2 3x - 4y = 100x - 8y = 18 -> -8y = 18 -> y = -18/8 = -9/4 -> 3x - 4*(-9/4) = 10 -> 3x + 9 = 10 -> 3x = 1 -> x = 1/3
Y equals 5x plus 18 y equals 2x plus 9?
5x+18 = 2x+9 5x-2x = 9-18 3x = -9 x = -3 and y = 3
1 divided by 3x plus 6 equals 9?
1/3x + 6 = 9 Restating the problem x + 18 = 27 I multiplied by 3 x = 9 I subtracted 18 from 27
How do you get y by itself in the equation 3x-6y equals 9?
