Question

i am trying to figure out the solution set for: 4(3 +4x)-5 greater than or equal to 151

Answer 1

Isolate x: \[4(3+4x)\ge156\]
\[(3+4x)\ge39\]
\[4xge36\]
\[x \ge 9\]

Answer 2

did you understand what she did?

Answer 3

i think i do. she first divided 156 by 4 getting the 39. then subtracted 3 from 39 to solve for x - dividing 36 by 4. it makes sense now.

Answer 4
