multiply both sides by 15 and simplify each fraction separately by cancelling common factors top and bottom. you will get 3(x+4) + 5(x+7)=9 then multiply out the brackets 3x + 12 + 5x + 35 = 9 obviously that's the same as 8x+47 = 9 so take 47 from both sides 8x =-38 giving x = 4 3/4
If the questions asks: (3)/(4x+2) = (5)/(4x-6) then x = -(7/4)
The sum of 3/8 and 2/5 is 31/40
143542make the variables X plus Y plus Zthe solution is X*Y,X*Z, then (X+Z)*Y flipped7*2=147*5=35(7+5)*2=24 flipped =421435425*3=155*2=10(5+2)*3=21...flipped =12151012
If: 6x-4+7 = 5 Then: x = 1/3
5 and 3/4
4/5 (4 over 5)
4/5 + 3/5 = 7/5
It is 4/8 plus 5/6 = 4/3
4 3/4 + 1/4 = 5.
3 1/4
I meant 6 4 over 5 plus 3 3 over 5
5/7 + 3/4 = 113/28
3/5 + 1/4 = 17/20
3 1/4 + 2 3/5 = 5 1/5
It is: 5/4 or 1.25
It is: 3/4+5/16 = 17/16 or 1.0625
