Answer:

5t - 18

Explanation:

STEP 1: Simplify 8/5

equation at end- 8 (7 - 3t) - (5 • ((0 - (— • t)) + 5)) 5

STEP 2: 2.1 Adding a whole to a fraction

Rewrite the whole as a fraction using 5 as the denominator :

5 5 • 5

5 = — = —————

1 5

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

\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:

-8t + 5 • 5 25 - 8t

——————————— = ———————

EQUATION AT END: (25 - 8t)

(7 - 3t) - (5 • —————————)

5

STEP 3: (7 - 3t) - (25 - 8t)
