You would need one more equation relation x and y to solve for both of them.
Equation: x^2+x=420 x^2+x-420=0 Using the quadratic formula, x=(-1+sqrt(1+4*420))/2 x=(-1-sqrt(1+4*420))/2 x=20 or -21
Close, but not exactly.420 ft X 210 ft = 88200 ft22 acres = 87120 ft2
X = 8
x = 1 divided by (a - 2.5)

2 x 2 x 3 x 5 x 7 = 420

No, it equals 420.
4 divided by x equals 10 = 0.4
1 x 420, 2 x 210, 3 x 140, 4 x 105, 5 x 84, 6 x 70, 7 x 60, 10 x 42, 12 x 35, 14 x 30, 15 x 28, 20 x 21 = 420

Yes, 1 can divide. Anything divided by 1 equals that number which was first divided. For example, x/1 = x. x divided by 1 equals x
X = 72 72 divided by 9 equals 8
x = 10000
