What is the solution for p in the equation?

Nookie1986 [14]

Answer:

p=-6

Step-by-step explanation:

the first thing to do is to add all like terms for example $\frac{1}{3}$ p+ $\frac{1}{2}$ p would turn into $\frac{2}{6}$ p+ $\frac{3}{6}$ p to make it so we can add them together which after we add both of those p's together we get $\frac{5}{6}$ p which now we have $\frac{5}{6}$ p+7= $\frac{7}{6}$ p+5+4 which now we add 5 and 4 which we get 9 which now the equation looks like $\frac{5}{6}$ p+7= $\frac{7}{6}$ p+9 which now we subtract 7 from 9 and we are left with 2 so now the equation is $\frac{5}{6}$ p= $\frac{7}{6}$ p+2 which now we subtract $\frac{7}{6}$ p from $\frac{5}{6}$ p and we are left with - $\frac{2}{6}$ p=2 which now we divide both sides by - $\frac{2}{6}$ which makes the equation look like p=2÷- $\frac{2}{6}$ which equals -6 so all we are left with is p=-6
