-11(10+11p)=-10(2+8p)+4p

Question

−11(10+11p)=−10(2+8p)+4p need help solveing

 

Answer 1

First thing to do is simplify both sides:

 

LEFT SIDE:  -11(10+11p) = -11*10 + -11*11p = -110 -121p

 

RIGHT SIDE:  -10(2+8p)+4p = -10*2 + -10*8o + 4p = -20 - 80p + 4p = -20 - 76p

 

Now you have a simpler equation:

 

-110 - 121p = -20 - 76p

 

Add 121p to each side:

-110 = -20 + 45p

 

Add 20 to each side:

-90 = 45p

 

Divide each side by 45:

-2 = p

 

So p = -2
