7th grade

hey im a 7th grade student and math (to be honest) is my worst subject, i have alot of trouble trying to do some complex things, like linear equations. i dont know why but they all seem confusing to me. 1. n- 25.4= -44.8 n= -19.4
 * interpreted graphs**
 * ALGEBRA:**

how i got this: well i first started with the number next to the variable, so i put that number (25.4) under the -44.8 because they are different signs (meaning negitive or postitve) i use K.O.O ( Keep. Oppisite. Oppisite) and changed the 25.4 into a negitive 25.4 then subract as usual, and got -19.4

2. eguations that can equal to negitive 14: -7+p=-14 p=-7

-21+a=-14 -29+r=-14 -8+a=-14 a=6 r=15 a=6
