    so -np-5<=4x-8

    -np - 5 ≤ 4(c - 2) np+5

    alright yes that's right you have to isolate n so move -5 to the right side and remember when you MULTIPLY or DIVIDE by negative number then you should flip the inequality sign

    np +5 >=- 4(c - 2) np >= -4c +8-5 np> = -4c+3

    np/p=-4c+3/p n>=4c-3/p

    -np - 5 ≤ 4(c - 2) -np - 5 ≤ 4c - 8 adding +5 for both sides -np=<4c-8+5 -np=< 4c-3 multiply by (-1) np >=-4c+3

    based on what ? \[\rm n \ge \frac{ -4c \color{reD}{+}3 }{ p }\] n ≥ - the quantity 4 times c **minus** 3 all over p

    or you can write it as \[\rm n \ge \frac{ 3 -4c }{ p }\] but still 3 is positive take a screenshot

    n ≥ - the quantity 4 times c minus 3 all over p \[\rm n \ge \frac{ -4c \color{reD}{-}3 }{ p }\] \[\rm n \ge \frac{ \color{reD}{-} (4c \color{reD}{+}3) }{ p }\] negative sign is common so take it out mhm

    Which equation is not equivalent to the formula e = mc? m equals e over c c equals e over m e = cm m equals c over e

    well sure i solve for m and c idk about the e=cm but that leaves us with m=c/e

    yes that's right m = c/e equal to em =c which is not equivalent to e =mc

    equation is e = mc m TIMES c and D is m = c/e which is em = c solve for e you will get e = m/c m OVER c
