Question

Step 1 :
49
Simplify ——
10
Equation at the end of step 1 :
21 37 49
((0-(——•x))+——)•(5+(——•x))
10 10 10
Step 2 :
Rewriting the whole as an Equivalent Fraction :
2.1 Adding a fraction to a whole

Rewrite the whole as a fraction using 10 as the denominator :

5 5 • 10
5 = — = ——————
1 10
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :
2.2 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:

5 • 10 + 49x 49x + 50
———————————— = ————————
10 10
Equation at the end of step 2 :
21 37 (49x+50)
((0-(——•x))+——)•————————
10 10 10
Step 3 :
37
Simplify ——
10
Equation at the end of step 3 :
21 37 (49x + 50)
((0 - (—— • x)) + ——) • ——————————
10 10 10
Step 4 :
21
Simplify ——
10
Equation at the end of step 4 :
21 37 (49x + 50)
((0 - (—— • x)) + ——) • ——————————
10 10 10
Step 5 :
Adding fractions which have a common denominator :
5.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

-21x + 37 37 - 21x
————————— = ————————
10 10
Equation at the end of step 5 :
(37 - 21x) (49x + 50)
—————————— • ——————————
10 10
Step 6 :
Final result :
(37 - 21x) • (49x + 50)
———————————————————————
100

what is the sum of (-2.1x+3.7) and 5+4.9x) would this be correct
