Question

Pls solve fast Thank You

Answer 1

1. sol:- x-3/5 + x-4/7 = 6- 2x-1/35 then,

lets take LCM on both the sides i.e LHS =RHS ,

=> x-3+x-4/35 = 210 -2x-1/35 => 2x-7/35 = 209-2x/35 => 2x-1 = 2x-1 hence proved ____________________________________________________________________2.solution:- given:-

=>0.4z-3/1.5z+9= -7/5 =>5(0.4z-3) =7(1.5z+9)

=>2z-15=10.5z+63

=>2z - 10.5z = 63 + 15

=>-8.5z = 78

=>z = 78/ -8.5

=>z= -156/17

=>z= -9.17 hence proved ____________________________________________________________________pls mark has brainliest;-)
