7x+y-9=0
move constant to the left by adding its opposite to both sides. the sum of the two =0
1st you distribute whats outaide the fractions 2/3*6 and 2/3*5/6 which would be 4 and 5/9 and then subtract those which would be 4/1 - 5/9 To make denomantor the same you would multiply 4/1 by 9 so it would be 36/9- 5-9= 31/9 which converts to 3 4/9. so your answer is 3 4/9
