5
five times the sum of a number and 8 is -15.
Suppose the number is x. The sum of the number and two is x+2 Four times the sum is 4(x+2) The number times 8 is 8x 24 less than the number times 8 is 8x-24 4(x+2) = 8x-24 4x+8=8x-24 so 4x = 32 and x = 8
3x + (-4) ≥ 2x + 8
8(5+4)+7 = 79
Y = 4 (x+8)

Not necessarily. If the number is 0, then the sum of 8 times the number and -192 is -192.
(3a-8) + 5x(a)

4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
4*(2x + 8) = 32
8 x (4+2) = 48
