I will solve you system by substitution
y = 2x - 3 ; x + y = 1
→Step 1: Solve y = 2x - 3 for y
→Step 2: Substitute 2x - 3 for y in x + y = 1:
x + y = 1
x + 2x- 3 = 1
3x - 3 = 1 (Simplify both sides of the equation)
3x - 3 + 3 = 1 + 3 (Add 3 both sides)
3x = 4
3x ÷ 3 = 4 ÷ 3 (Divide each side by 3)
x = 4/3
→Step 3: Substitute 4/3 for x in y = 2x - 3:
y = 2x - 3
y = 2 (4/3) -3
y = -1/3 (Simplify both sides of the equation)
Answer:
x = 4/3 and y = -1/3

Answer:
1680 miles
Step-by-step Explanation:
There are 52 weeks in a year. Total number of days she is expected to work would be 52 * 5 = 260 days.
Now we know she has 10 vacation days and 10 holidays. This translates 260 - 20 = 240 days
Now if she drives 35miles 5 days of the week, this means she dives 7 miles per day.
The total number of miles traveled is this 240 * 7 = 1680 miles
