The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32

According to the statement twice a number minus 2 is 8 the answer is 5.
((2n + 8)) x 5 = 6n + 12ie 10n + 40 = 6n + 124n = -28n = -7(both equations total -30)
If: 2x+8 = 7 then x = -1/2
The answer is -32 Sum of -16+8 = -8 Half of -8 = -4 Sum of -5+9 = 4 Twice of 4 = 8 Product = 8*(-4) = -32
to sum two numbers you add them together then to get twice that you multiply the sum by 2 e.g. if the two numbers are 5 and 8 the sum = 5 + 8 = 13 twice that is 13 x 2 = 26
4(x + 5) = 2x + 8 4x + 20 = 2x + 8 2x = -12 x = -6
2n + 8 = 33
If the sum of a number and 4 is (X + 4) then twice that is 2(X + 4) which is 2X + 8
five times the sum of a number and 8 is -15.
The sum of 8 and 5 is 13. There is then no number with which to calculate its product.
This is simple algebra. Let the unknown number be n. Then the sum of this number and 8 = n + 8.

18. 1+8=9 9x2=18
3x + (-4) ≥ 2x + 8
