    \[\frac{ 7 }{ 8 } - \frac{ 1 }{ x } = \frac{ 3 }{ 4 }\]

    Do the follow 7/8-3/4=1/x 7-6/8=1/x 1/8=1/x Now you can try to finish;)

    so we have \[\frac{ 1 }{ 8 } = \frac{ 1 }{ x }\] just to make sure

    Solve for x: 2 over quantity x plus 2 plus 1 over 5 equals 6 over quantity x plus 5. x = 0 x = –13 x = 13 x = 0 and x = 13

    \[\frac{ 2 }{ x + 2 } + \frac{ 1 }{ 5 } = \frac{ 6 }{ x + 5 }\]

    Use minimum multiple common (5.2)+(x+2)/5x+10= 6/x+5 10+x+2/5x+10=6/x+5 12+x/5x+10=6/x+5 (12+x).(x+5)=6.(5x+10) Now you can try to solve the rest

    Look you made a mistake somewhere 12x+60+x^2+5x=30x+60 17x+60+x^2=30x+60 X^2+17x=30x X^2-13x=0 So X(x-13)=0 X=0 Or X=13

    Solve for x: 3 over 3 x plus 1 over quantity x plus 4 equals 10 over 7x . x = –3 x = 3 x = –3 and x = 3 No Solution
