42 72
The answer to 7 x 6 plus 9 is 51. You have to multiply 7 by 6 which equals 42 and add 9 onto it which equals 51.
42 + 42 = 84

They are equal. 7 squared is 7 x 7, which equals 49. 6 x 7 = 42, plus another 7 = 49.
49 x2 + 14x = -7 x2 + 14x + 49 = 42 (x + 7)2 = 42 x = -7 ± √42
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
5X + 7 = 42 subtract 7 from each side 5X + 7 - 7 = 42 - 7 5X = 35 divide both sides integers by 5 (5/5)X = 35/5 X = 7 ----------check in original equation 5(7) + 7 = 42 35 + 7 = 42 42 = 42 --------------checks
10x + 7 = 4x + 49 6x + 7 = 49 6x = 42 x = 6
28 + 42 = 70
42 and 42
It is: 38+4 = 42
13 + 42 = 55
40+48=88. 81 + 7 = 88...
7x + 9 = 51 7x = 42 x = 42/7 = 6
