Best ResponseYou've already chosen the best response.0\[\frac{ x }{ 6 }=\frac{ x }{ 7 }+5\] to better understand here is the actual problem in the correct equation

Best ResponseYou've already chosen the best response.1Move the x's to one side. Make the denominators equal. Minus the two terms, and move the denominator over to the over side and multiply 5 by the denominator (42) and then divide by the number next to x on the side where 5(42) is. and voila

Best ResponseYou've already chosen the best response.0\[\frac{ x }{ 6 }=\frac{ x }{ 7 }+5\] Multiply both sides by 42 (least common multiple of 6 and 7), to obtain 7x = 6x + 210 ∴ x = 210 Do you understand?

Best ResponseYou've already chosen the best response.0would it look like x/42?

Best ResponseYou've already chosen the best response.1but in order to make the denominators equation, you need to times the numerator by the amount that the denominator needs to make 42. eg. 6 X ? = 42 (7) so times the top x by 7 which becomes 7x. and the other becomes 6x since you need to times 7 by 6 to make 42. so it would be 7x/42  6x/42 7x6x = x so it will eventually become x/42

Best ResponseYou've already chosen the best response.0i have even harder ones... like \[\frac{ x}{ 2x+2 }=\frac{ 2x }{ 4x+4 }+\frac{ 2x3 }{ x+1 }\]

Best ResponseYou've already chosen the best response.1You use the same principle: so to add two fractions, the denominators must be the same. make the denominator under 2x simplified: 4x + 4 4(x+1) and use {2x over 4(x+1)} + {4(2x3) over 4(x+1)} as a first step

Best ResponseYou've already chosen the best response.1um... you could do it like this: \[{3 \over y4} = {2 \over y^2 16}\] \[{3 \over y 4} = {2 \over (y+4)(y4)}\]

Best ResponseYou've already chosen the best response.1Then knock off the y4 so you're left with \[3 = {2 \over y+4}\]
