Question

please give solutions

Answer 1

d)x+5/2+x-5/3=25/6

=3×+15+2×-10(upon 6)=25/6

=3x+2x+15-10=25/6

=5×+5

Answer 2

b) 3x + 8/2x + 7 = 4

3x + 8 = 4(2x + 7)

3x + 8 = 8x + 28

3x - 8x = 28 - 8

-5x = 20

x = 20/-5

so, x = -4

c) (2/3x) - (3/9x) = (1/12)

18x-9x / (27x square) = 1/12

9x / (27x square) = 1/12

72x = (27x square)

72/27 = (x square) / x

x = 24/9

so, x = 8/3

d) [(x+5)/2] + [(x-5)/3] = 25/6

[3(x+5) + 2(x-5)] / 6 = 25/6

[(3x+15) + (2x-10)] / 6 = 25/6

(5x+5) / 6 = 25/6

6(5x+5) = 25 × 6

30x + 30 = 150

x + 1 = 5

x = 5 - 1

so, x=4

e) 4(2b-3) + 5(3b-4) = 14

8b - 12 + 15b - 20 = 14

23b - 32 = 14

23b = 14 + 32

23b = 46

b = 46/23

so, b = 2
