Can't solve the graph for the solution set.

4x+2 <3x-5

Should be greater or equal to sign after the 2 and before the 3

4x+2 <= 3x-5

One for free. Next time, show your work.

4x+2 <= 3x-5

Subtract 2

4x+2-2 <= 3x-5-2

Simplify

4x <= 3x-7

Subtract 3x

4x-3x <= 3x-3x-7

Simplify

x <= -7

Hello valesat99!



Can't solve the graph for the solution set.

4x+2 >3x-5

Should be greater or equal to sign after the 2 and before the 3


Given:4x+2\ge3x-5
Get the x's on one side:x+2\ge-5
Get the "regular numbers" on one sidex\ge-7

6x+4(3x-2)=6x+2

6x+4(3x-2)=6x+2You seem to have missed this part: "One for free. Next time, show your work."
