The answer is that the value of x is -21
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
1 x 21, 3 x 7.
The answer is 42. 6 x 7 equals 42. 21 x 2 equals 42.
x + 21 = 36Subtract 21 from each side:x = 15
x = ab x = 21*37 x = 777
The answer is that the value of x is -21
x ≠11 9 + x = 21 9 + x - 9 = 21 - 9 x = 12
1 x 21, 3 x 7.
21 = 1 x 21, 3 x 7, 7 x 3, 21 x 1.
The answer is 42. 6 x 7 equals 42. 21 x 2 equals 42.
x=-7
x + 21 = 36Subtract 21 from each side:x = 15
21/x = 105/5 = 21 21 = 21x x = 1
If 7x = 21, then x=3 !
y = kx k = y/x = 21/-5 = - 21/5
This is not correct. If x=11, then 9+x=20. In order for 9+x=21 to be correct, x would have to be equal to 12.
