Two times the difference of 13 and a number is -4. Write an
equation representing this
situation and solve for the
number.

Step-by-step explanation:

let number be x

CASE 1) when x>13

2(x-13) = 4

2x - 26 = 4

2x = 30

x = 15

CASE 2) when x<13

2(13 - x) = 4

26 - 2x  = 4

26 - 4 = 2x

22 = 2x

11 = x

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
