Solve the inequality
|r+3|> 7

Absolute value so the answer can be positive or negative
R+3>7
-3>-3
R>4
Or
R-3>7
+3>+3
R>10

Answer
410

For
|a|>b, solve for the value that make a true for
a>b and a<-b

|r+3|>7
solve
r+3>7 and r+3<-7
minus 3 both sides in both equations
r>4 and r<-10

the solution is r>4 or r<-10, basically r can be any real number except for from -10 to 4

r>4 or r<-10
