Question

solve the equation and check your solution by substituting in the equation 6x-9-2(1-x)=x+9

Answer 1

6x-9-2+2x=x+9
8x-11=x+9
8x-x=9+11
7x=20
x=20/7

Answer 2

Hey
your answer is-
________________________________
solution -

6x-9-2(1-x)=x+9
6x-9-2+2x=x+9
8x-11=x+9
8x-x=9+11
7x=20
x=20/7


verification

put x=20/7

6×20/7-9-2(1-20/7)=20/7+9
=>120/7-9-2+40/7=20/7+9
=>(120-63-14+40)/7=(20+63)/7
=>(160-77)/7=83/7
=>83/7=83/7
LHS= RHS
