$p=10$

Given: $7+10p=107$

Subtract $7$ from both sides.

$color(red)cancelcolor(black)7-color(red)cancelcolor(black)7+10p=107-7$

$10p=100$

Divide by $10$ .

$(color(red)cancelcolor(black)10p)/(color(red)cancelcolor(black)10)=100/10$

$p=10$

$p=10$

Move all like terms to the same side:

$7color(red)(-7)+10p=107color(red)(-7)$

$10p=100$

Divide:

$(10p)/10=100/10$

$p=10$
