on the days he worked overtime, he was paid 95 dollars.
on the days he didn't work overtime, he was paid 80 dollars.
x = number of days he worked overtime.

his total compensation was 95 * x + 2 * 80 = 1870 dollars.
simplify to get 95 * x + 160 = 1870
subtract 160 from both sides of the equation to get 95 * x = 1710
solve for x to get x = 18.

he worked 18 days at 95 per day and 2 days at 80 per day for a total of 1870 dollars.

18 * 95 = 1710
2 * 80 = 160
1710 + 160 = 1870.

solution is that he worked a total of 20 days, 18 at 95 per day and 2 at 80 per day.

Assume he works totally for x days
he gets $80 per day
$15 overtime except 2 days
TOTAL =$1870
equation
80x +15*(x-2)=1870
80x +15x-30 =1870
95x-30=1870
95x = 1870+30=1900
95x =1900
x=1900/95
x=20
two days no overtime
18*15=270
he earned $270 on overtime.
check if i am right

Informally....

If he had worked overtime on those other two days also, he would be making $80+$15 = $95 every day, and his total earnings would have been $1870+2($15) = $1900.

$1900 at $95 per day means the number of days he worked was $1900/$95 = 1900/95 = 20.

So he worked 20 days, with overtime on 18 of those days.

ANSWERS:
(a) He worked for a total of 20 days
(b) His pay from overtime was 18($15) = $270

The description can be arranged into a constant rates table.
d, the variable for number of days he worked; "regular" pay goes for each day,
regardless of if done overtime or not.
PAYRATE               DAYS          MONEY
 80 regular            d
 15 overtime           d-2

TOTAL                               1870


Fill the missing MONEY data.
PAYRATE               DAYS          MONEY
 80 regular            d             80d
 15 overtime           d-2          15(d-2)

TOTAL                               1870

Equation to solve, highlight_green%2880d%2B15%28d-2%29=1870%29

As the problem is worded in the post, its formulation is DEFECTIVE.

To be correct, the problem should be re-formulated in this way

    Victor is paid $80 per day. In addition he is paid $15 for each day he works overtime. 
    If he worked overtime each day except for 2 days, when he worked regular hours, and earned a total of $1,870.00,
    - how many days did he work to earn this amount ?
    - the amount of money he earned from overtime only ?

My addition is the underlining terms.
