Answer:
45 miles
Step-by-step explanation:
Since she drives a total of 3 hours traveling 15 miles each hour you just multiply 15 times 3
The best possible first step would be to multiply equation one by 4 and equation by 5 that would eliminate the y and allow you to solve for x.
In essence, 4 × (3x + 5y = 1) eq1
5 × (2x + 4y = -4) eq2
thus giving rise to 12x + 20y = 4 eq1 × 4
10x +20y = -20 eq2 × 5
You can then just subtract one equation from the other
For example, (12x + 20y = 4) - ( 10x +20y = -20 )
12x - 10x + 20y - 20y = 4 - (-20)
2x = 24
x = 12
