The second step is wrong. What should've been done is to find greatest common factor (gcf) of 1/6 and -2. This is because you cannont add together a number with a variable to a number without a variable. So get the variable by itself by subtracting 1/6 from both sides.
1/5x + 1/6 = -2
___— 1/6_— 1/6
____________
Turn -2 into a fraction and find the gcf of -2 and 6:
1/5x + 1/6 = -2
___— 1/6_— 1/6
____________
1/5x = -2/1 — 1/6 ——> 1/5x = -12/6 — 1/6
1/5x = -13/6
Then divide each side by 1/5 to get the variable by itself; remeber: when dividing a fraction by a fraction, you multiply by the reciprocal.
5/1 • 1/5x = -13/6 • 5/1
x = 65/6
Then, simplify
65/6} 10.83 or 10 83/100

Answer:
95
Step-by-step explanation:
if you see that line in between 90, 100 that is a five and it is past 90 making it 95
Answer:
127 per day
Step-by-step explanation:
Total pushups in 4 weeks = 3,556
4-week period( 7 days a week) = 4 × 7
= 28 days
How many push-ups did Joey do each day?
Push ups per day = Total push ups / Total number of days
= 3,556 / 28
= 127
Push ups per day = 127
Joey did 127 push-ups each day for a 4-week period( 7 days a week)
