Question

Solve the inequality. |r + 3| ≥ 7

Answer 1

R+3>7
-3 -3
r>4
just write it right I couldn't find the same sign

Answer 2

Solve the equation just like you for any ordinary equation. Leave the inequality sign as it should be and transpose like terms.

r + 3 ≥ 7
r ≥ 7 - 3
r ≥ 4

Thus, the value of r must be less than or equal to 4. Its range would be (-∞, 4]. 

I hope I was able to explain it clearly. Have a good day.
