Question

2x + 1 is less than or equal to x +5
{x|x is less than or equal to ?

Answer 1

X is les than or equal to 4.

First we substract the one from the left side to the 5 on the right side, giving us +4. Then we bring the x on the right side to the left by substracting it from 2x.. which gives us 1x. putting the Equation together we get x is less than or equal to 4. We dont have to change the inequality sign because wee didn't DIVIDE with a negative.

Answer 2

Thank you very much!
