Simplify both sides of the equation 34+p+112=78-7 34+p+112=78+ - 7 (P) + (34+112) = (78+ - 7 ) Combine like terms P+146=71 Subtract 146 from both sides P+146-146 = 71-146 P= -75 I do it for you step by step so you the teacher can see where you found that answer . It's not just put -75 , that's not help . So let me know if you got it or not ?
