Split it into 2 equations
2x-9 = 7
2x = 16
x = 8
And another equation
2x-9 = -7
2x = 2
x = 1
The answer is x =1, x= 8

You should check my answers though, I may have mixed up some terms.
Those are mixed number
<span>3 1/3 + 1 1/4
10/3+5/4
take LCM
40+15/12
55/12=4.5833 or u can write in mixed form 4 7/12</span>
