Answer:
25. x = -7
33. x = -1/3
43. x = 1/4
Step-by-step 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
