Answer:
x = -3, y = -4
(-3, -4)
Step-by-step explanation:
solve each equation for y (the first equation is already solved for y, so just do the second equation)
-x -y =7
<u>+x +x</u>
-y = x + 7 eliminate the negative by switching all signs
y = -x - 7
now that both equations equal y, you can set them equal to each other:
-x - 7 = 3x + 5
solve for x
-x - 7 = 3x + 5 move the variable to one side of the equation
<u>+x +x </u>
-7 = 4x + 5 move the constant to the other side of the equation
<u>-5 -5</u>
-12 = 4x single out x by dividing the whole thing by 4
<u>÷4 ÷4</u>
-3 = x
now substitute -3 for x in one of the original equations (it doesn't matter which equation)
y = 3(-3) +5 solve
y = -9 +5
y = -4
have a wonderful day! :)
Answer:
900 miles long
Step-by-step explanation:
Given data
Le the total mile of the trip be x
Autumn fell asleep at 39% of the trip, which is equal to 351 miles
so
=39/100*x= 351
0.39x= 351
divide both sides by 0.39
x= 351/0.39
x= 900 miles
Hence the trip is 900 miles long
