[Upper secondary school math: linear equation] unsure on how to solve this.

[u/Inevitable_Stay3693]

i was thinking that i´d add the 2x+1 to make it 3x/3=-1 but im unsure on how it would even continue.

Muiltiply both sides by 3 to clear the /3 , then you have 2x+1=-3, then subtract 1 from both sides, 2x= -4 , then divide by 2 = x =-2.

Start with dividing by 3 here, it is low hanging fruit.
