Answer:

{-7, 13}

Step-by-step explanation:

|R-3| = 10

| | Distance to 0, so hypothetically |-1| = |1|

R-3 = 10 and -(R-3) = 10

R-3 = 10        R-3=-10

 +3    +3         +3   +3

R=13               R=-7

Answer:

{-7, 13}

Step-by-step explanation:

|R - 3| = 10

There are two cases, one positive and one negative

R - 3 = 10  and R-3 = -10

Add 3 to each side

R - 3+3 = 10+3  and R-3+3 = -10+3

R = 13                       R = -7

The solution set is {-7, 13}
