Answer:

1362−271x/4

Explanation:

STEP 1 :

Equation at the end of step 1

(3/4 * (3x+6))-14*(5x-24)

STEP 2 :

Simplify 3/4

Equation at the end of step 2 :

3

(— • (3x + 6)) - 14 • (5x - 24)

4

STEP

3

:

STEP

4

:

Pulling out like terms

4.1 Pull out like factors :

3x + 6 = 3 • (x + 2)

Equation at the end of step

4

:

9 • (x + 2)

——————————— - 14 • (5x - 24)

STEP

5

:

Rewriting the whole as an Equivalent Fraction

5.1 Subtracting a whole from a fraction

Rewrite the whole as a fraction using 4 as the denominator :

14 • (5x - 24) 14 • (5x - 24) • 4

14 • (5x - 24) = —————————————— = ——————————————————

1 4

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 :

5.2 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:

9 • (x+2) - (14 • (5x-24) • 4) 1362 - 271x

—————————————————————————————— = ———————————

4 4

Final result :

1362 - 271x

———————————

4
