Need 25,33,43 BY 2:00!

Answer 1

25. x= -7

33. x= -1/2 (the “-“ can be on top or bottom)

43. x= 1/4

Answer 2

25. x = -7

33. x = -1/3

43. x = 1/4

Explanation:

25. 3/7x + 2 = -4/7x - 5 (get all likes on the same sides of equal sign)

3/7x + 4/7x = -5 - 2

7/7x = -7 (7/7 is = 1)

1x = -7

x = -7

33. 3/8x - 1/6 = -5/8x - 2/3 (get all likes on the same sides of equal sign)

3/8x + 5/8x = -2/3 + 1/6

8/8x = -2/3(2/2) + 1/6 (get a common denominator)

1x = -4/6 + 1/6

x = -3/6

x= -1/3

43. x - 2/5 = -3/20

x= -3/20 + 2/5

x = -3/20 + 2/5 (4/4) (get a common denominator)

x = -3/20 + 8/20

x = 5/20

x = 1/4
