y = 304, just add 63 to each side
x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
The answer is the number for 'y' that makes the equation a true statement.Here's how to find it:63 - y = 2y + 3Add 'y' to each side:63 = 3y + 3Subtract 3 from each side:60 = 3yDivide each side by 3:20 = y
No you can't. There is no unique solution for 'x' and 'y'. The equation describes a parabola, and every point on the parabola satisfies the equation.

x*y = k where k is a constant.When x = 9, y = 7 so k = 9*7 = 63 When x = 21, 21*y = 63 so y = 3.
9x-3y=63 7x-3y=45 -3y=63-9x -y=21-3x y=-21+3x 7x-3(-21+3x)=45 7x+63+9x=45 7x+9x=45-63 16x=-18 x=-1.125 y=-21+3(-1.125) y=-24.375 (-1.125,-24.375)
7x - 9y = -63.When y = 0 then the resultant answer provides the x intercept.7x - 0 = -63 : x = -9When x = 0 then the resultant answer provides the y intercept.0 - 9y = -63 : y = 7Alternatively, to ascertain the y intercept convert the equation into the form y = mx + c, c is the y intercept.7x - 9y = -63 : -9y = -7x -63 : 9y = 7x + 63 : y = 7/9x + 7
The answer is the number for 'y' that makes the equation a true statement.Here's how to find it:63 - y = 2y + 3Add 'y' to each side:63 = 3y + 3Subtract 3 from each side:60 = 3yDivide each side by 3:20 = y
lets call the one number X and the other Y so y equals 3X so 3X plus X equals 84 so 4X equals 84 we divide by 4 so x equals 21 so y equals 21 times 3 equals 63 so the two numbers are 63 and 21
a+b=84 a=3b 3b=84-b 4b=84 b=21 a=3*21 a=63 The two numbers are 21 and 63lets call the one number X and the other Y so y equals 3X so 3X+X equals 84 so 4X equals 84 we divide by 4 so x equals 21 so y equals 21*3 equals 63 so the two numbers are 63 and 21
what x3 equals 63 is:21x3=63
what equals 63
63-84 equals = -21
