7p-(3p+4)= -2 (2p-1)+10

7p ( -3p +4) = -2 ( 2p - 1) + 10

so ima do one part first okay.

7p x -3p = -21p

7p x 4 = 28p

so now we put it as a equation. so you have now
-21p +28p = -2 (2p -1) +10

so ima do the second part.
-2 x 2p = -4p
2 x 1 = 2

so now you have -21p + 28p = -4p + 2 + 10

so im going to put all like terms together.

28p - 21p = 7p

7p = -4p + 2 + 10
+4p  +4p

11p = 2 + 10
 
 11p = 12                 
         11 

p = 12/11 *it's your answer

The variables should add up to equal 1
