X = {0, 2, 4, 6, 8}.
=> f(x) = 2x - 1
x f(x) = 2x - 1
0 2*0 - 1 = - 1
2 2*2 - 1 = 3
4 2*4 - 1 = 7
6 2*6 - 1 = 11
8 2*8 - 1 = 15
Answer: {-1, 3, 7, 11, 15}
The original number would be 48. 12 multiplied by 4 is 48, and if you add a three to that you will get 51.
Hope this helped :)
Yes, if you just distribute 2(x-6). Then you would have 2x-12 = -35 then add 12 to the -35 and your answer would be 2x = -23 and leads to them being equivalent.
