Solution equation: (x + 6) (x + 5) - (x-1) (x + 4) = - 24

Solution equation: (x + 6) (x + 5) - (x-1) (x + 4) = - 24

solve equations:
(x+6)(x+5)-(x-1)(x+4)=-24
x²+11x+30-x²-3x+4=-24
8x=-58
x=-29/4

82 minus three times x is 19 how to do

82 minus three times x is 19
82-3x=19
3x=82-19
3x=63
x=21

3, 4, 19, 94, x, what's x

3,4,19,94, x, consider this way: 4 is more than 3 by 1, which can be regarded as 1 * 1, 19 is more than 4 by 15, which can be regarded as 3 * 5, 94 is more than 19 by 75, which can be seen as 5 * 15; note that the multiplier here is 1,3,5 respectively; the multiplicand here is 1,5,15 respectively, so the following number should be 7 * 25 = 175
