12+2x+3(x-5)=12+2x+3x-15
12+2x+3(x-5)=12+2x+3x-15
12+2x+3x-15=12+2x+3x-15
12+2x+3x-15=12+2x+3x-15
12+2x+3x-15=12+2x+3x-15
12+2x+3x-15=12+2x+3x-15
This equation will have infinitely many solutions if the two sides of the equation become equal after simplification.
Therefore, the complete equation should be: 12+2x+3(x-5)=12+2x+3x-15
Complete the equation so that it has infinitely many solutions: 12+2x+3(x-5)=
