Answer 20

so you need to find the lcd(least common denominator) after that you have to multiply the bottom numbers by anumber to make them all the same. The LCD is 6x because all the bottom numbers can be made into 6x, so we multiply 3x by 2, 3 by 2x, and 2x by 3. After that you have to do the same to the top as you did to the bottom. so 10 multiply by 2, 4 times 2x and (7+x) times 3. so this is how it looks after This is how the new equation looks\[\frac{ 20 }{ 6x}+\frac{ 8x }{ 6x }=\frac{ 21+3x }{ 6x }\]
