    ok good.. :D if its a mixed number changed the whole number to fraction with the same denominator so no prob on these .. 1 1/3 =is this like 1*3/3 +1/3 = 3/3 + 1/3 = 4/3 yes? 3 1/4 = 3*4/4 + 1/4 = 12/4 + 1/4 = 13/4 yes ? , 2 1/3 = 2*3/3 + 1/3 = 6/3 + 1/3 = 7/3 yes ? if yes now you can do the prob

    -1/7=x + 1 2/3 since the denominator are 7, t and 3 the common denominator is 7x3=21 \[\frac{ -1 }{ 7 }*\frac{ 3 }{ 3 } - \frac{ 5 }{ 3 }*\frac{ 7 }{ 7 }\] \[=\frac{ -3 }{ 21 }- \frac{ 35 }{ 21 }=\frac{ -38 }{ 21 } yes or no?\]

    \[3\frac{ 1 }{ 4 }= 2\frac{ 1 }{ 3 }+R\] \[3\frac{ 1 }{ 4 }-2\frac{ 1 }{ 3 }=R \] the common denominator is 4x3 =12, therefore \[=3*\frac{ 4 }{ 4 }+\frac{ 1 }{ 4 }-2*\frac{ 3 }{ 3 }+\frac{ 1 }{ 3 }\]

    are you gonna be comfortable if we do them like these? 3 1/4 = 2 1/3 +R 13/4 = 7/3 +R common denominator is 4x3=12 13/4 - 7/3 =R 13/4 *3/3 - 7/3 *4/4 =R 39/12 - 28/12 =R 11/12=R yes?

    -1/7=x+1 2/3 -1/7=x+ 5/3 -1/7- 5/3=x, LCD=21 (-1/7)(3/3)- (5/3)(7/7)=x, -3/21 - 35/21 =x x= -38/21 yes?

    y - 8 = 35 y - 8 + ? = 35 + ? add 8 on both sides y - 8 + 8 = 35 + 8 y+0= 35+8 y= ?
