Step-by-step explanation:

Simplify the following:

(3 x)/5 - 320 x - 7 + 19

Hint: | Put the fractions in (3 x)/5 - 320 x - 7 + 19 over a common denominator.

Put each term in (3 x)/5 - 320 x - 7 + 19 over the common denominator 5: (3 x)/5 - 320 x - 7 + 19 = (3 x)/5 - (1600 x)/5 - 35/5 + 95/5:

(3 x)/5 - (1600 x)/5 - 35/5 + 95/5

Hint: | Combine (3 x)/5 - (1600 x)/5 - 35/5 + 95/5 into a single fraction.

(3 x)/5 - (1600 x)/5 - 35/5 + 95/5 = (3 x - 1600 x - 35 + 95)/5:

(3 x - 1600 x - 35 + 95)/5

Hint: | Group like terms in 3 x - 1600 x - 35 + 95.

Grouping like terms, 3 x - 1600 x - 35 + 95 = (95 - 35) + (3 x - 1600 x):

((95 - 35) + (3 x - 1600 x))/5

Hint: | Combine like terms in 3 x - 1600 x.

3 x - 1600 x = -1597 x:

(-1597 x + (95 - 35))/5

Hint: | Evaluate 95 - 35.

95 - 35 = 60:

(60 - 1597 x)/5
