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
lara [203]

Answer:

  1. v = 8
  2. x = -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

<em>Check</em>

  -2(8) -7 = -23 . . . . true

___

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

  x/4 = -3 . . . . . . . add 5

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

<em>Check</em>

  (-12/4) -5 = -8 . . . . true
