1. –2v – 7 = –23 (1 point) 15 8 –8 –15 2. start fraction x over 4 end fraction – 5 = –8 (1 point) –27 –12 –7 12

Step-by-step explanation:

1. I like to work with positive numbers, so the first thing I'd do is multiply the equation by -1.

  2v + 7 = 23

  2v = 16 . . . . . subtract 7

  v = 8 . . . . . . . divide by 2

Check

  -2(8) -7 = -23 . . . . true

___

2. (x/4) -5 = -8

  x/4 = -3 . . . . . . . add 5

  x = -12 . . . . . . . . multiply by 4

Check

  (-12/4) -5 = -8 . . . . true

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363

12

step-by-step explanation:

12 + 5 = 17

12x2=24

24-7=17
