Question

(x-3).(2y+1)=13 rezolv please!

Answer 1

Good morning

(x-3)(2y+1)=13

Now let's start by adding 3 to both sides

2xy+x-6y-3+3=13+3

2xy+x-6y=16

Now we need to add 6y to both sides

2xy+x=6y+16

2xy+x=6y+16

Now let's factor out the variable x

x(2y+1)=6y+16

Now we gonna have to divide both sides by 2x+1 so we can find the value for x

x(2y+1)/2y+1= 6y+16/2y+1

x= 6y+16/2y+1

I hope that's help :)
