first solve multiply ie..42-21 then subtractso it will come 21 ans
no.. x equals 11
T = 3x + 7y; x = 4; y = 6T = 3x + 7y (substitute 4 for x, and 6 for y)T = 3(4) + 7(6) = 12 + 42 = 54
y=7+x =x=7-x
It is f(x) = 7/x.
if the equation was 7x = 42. The answer would be x = 6
The answer is 42. 6 x 7 equals 42. 21 x 2 equals 42.
7x = 42 so x = 42/7 and therefore x = 6
x = 42 / 6Therefore x = 7
7x=42 x=42/7 or, x=6
6x=42 x=42/7 x=6
It is 7 times 6 = 42
The answer is 7
6x - 7 = 35 Therefore, 6x = 42 x = 42/6 x = 7
7 times six equals 42. Hope I helped! :)
42 + x2 = 13x ∴ x2 - 13x + 42 = 0 ∴ (x - 6)(x - 7) = 0 ∴ x ∈ {6, 7}
7 times 6 = 72
