Answer:
2.7
Step-by-step explanation:
x/2-1/5=x/3+1/4
find lcm and factorise fractions
=5x-2/10 =4x+3/12
cross multiply
10(4x+3) = 12(5x-2)
open brackets
=40x+30 = 60x-24
subtract 40x from both sides
40x-40x+30=60x-40x-24
30=20x-24
add 24 to both sides
30+24 = 20x-24+24
54 = 20x
divide both sides by 20
54/20 = 20x/20
2.7 = x
∴x=2.7
