Answer:

846x + 2123

—————

423

Explanation:

STEP

1

:

8

Simplify ———

423

Equation at the end of step

1

:

8

(2x + 5) + ———

423

STEP

2

:

Rewriting the whole as an Equivalent Fraction

2.1 Adding a fraction to a whole

Rewrite the whole as a fraction using 423 as the denominator :

2x + 5 (2x + 5) • 423

2x + 5 = —————— = ——————————————

1 423

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:

(2x+5) • 423 + 8 846x + 2123

———————————————— = ———————————

423 423

Final result :

846x + 2123

———————————

423
