15 x 3 = 45, 12 x 2 = 24, 45 + 24 = 69
x = 45
It depends on what x and y are.
(x-12)^2= 45 x^2 - 24x + 144 = 45 x^2 - 24x + 99 = 0 Using quadratic formula : (24 +/- (180)^0.5) / 2 In exact terms (using surds) = 12 +/- 3 x (5)^0.5 OR = 18.7 or 5.29

1 x 2 + 22 = 6, 4 x 5 + 52 = 45, 3 x 6 + 62 = 54.... 72 = 7 x 2 + 22 = 18
45 - 12 equals = 33
45 30/12 = x/18; 12x = 30 x 18; 12x = 540; x = 540 ÷ 12 = 45
15 x 3 = 45, 12 x 2 = 24, 45 + 24 = 69
x = 45

the answer is 2.6 because: 45 x X = 126 so you bring the 45 to the other side of equals, then it becomes a divide. X=126 divided by 45 soo.. X=2.8
45 x 12 = 540
45 x 1,943.42222 = 87,454
x equals 9
