Right_M = L.C.M / R_Deno = 2
Making Equivalent Fractions :
3.3 Rewrite the two fractions into equivalent fractions
Two fractions are called equivalent if they have the same numeric value.
For example : 1/2 and 2/4 are equivalent, y/(y+1)2 and (y2+y)/(y+1)3 are equivalent as well.
To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.
L. Mult. • L. Num. 17x —————————————————— = ——— L.C.M 10 R. Mult. • R. Num. 21 • 2 —————————————————— = —————— L.C.M 10
Adding fractions that have a common denominator :
3.4 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
17x + 21 • 2 17x + 42
———————————— = ————————

Making Equivalent Fractions :
5.3 Rewrite the two fractions into equivalent fractions
L. Mult. • L. Num. -47 • 2 —————————————————— = ——————— L.C.M 10 R. Mult. • R. Num. (17x+42) —————————————————— = ———————— L.C.M 10
Adding fractions that have a common denominator :
5.4 Adding up the two equivalent fractions
-47 • 2 - ((17x+42)) -17x - 136
———————————————————— = ——————————
10 10
Step 6 :
Pulling out like terms :
6.1 Pull out like factors :
-17x - 136 = -17 • (x + 8)
Equation at the end of step 6 :
-17 • (x + 8)
