65x+87x+42x=
First, let's find a common denominator for 4, 8, and 6: it's 24.
Now, we'll multiply each fraction by the appropriate number to get:
6×45×4x+8×37×3x+4×62×6x=
Let's solve the multiplication exercises in the numerator and denominator:
2420x+2421x+2412x=
We'll connect all the numerators:
2420+21+12x=2441+12x=2453x
Let's break down the numerator into a smaller addition exercise:
2448+5=2448+245=2+245=2245x
2245x
