Step-by-step explanation:
X=3
y=5
You have to cancel out either the x values or the y values (I chose y). You multiply both equations by particular numbers so either the x values or y values can be equal to each other, as well as positive or negative to each other. I multiplied -7y by 4 and 4y by 7, and got -28y and 28y. I then canceled those out. The numbers you multiply by also affects the rest of the equations, so I ended up with 48x=4 and -35x=35. After that, you combine like terms, which results in 13x=39. You divide 13 by both sides and you end up with x=3. To find y, all you have to do is plug in the x value to one of the equations, then solve for y. I resulted in y=5.
Hope this helped ^_^
Answer:
L=193
Step-by-step explanation:
Initial length of the road =57mi
L= Total length
D=number of days worked
Number of miles added in 1 day= 4mi
Therefore,
L=57+D*4
After 34 days,
L=57+(34*4)
L=193mi
