Question

Peter says, "If you subtract 16 from my number and multiply the difference by - 2, the result is

Answer 1

Let’s say Peter’s number is P.

P minus 16 and the answer times -2 is -34

-2(P-16) = -34

-2P+32 = -34

-2P = -66

Divide by -2

P is 33.

Check: 33-16 is 17 and 17*-2 is -34. So

P is 33.

Answer 2

Answer:

33

Step-by-step explanation:

Let the number be x,

=> (x - 16) -2 = - 34

=> -2x + 32 = -34

=> -2x = - 34 - 32 (by transposing)

=> -2x = -66

=> x = -66/-2 = 33

Peter's number is 33.
