1. we can add them to eliminate y's
3x-4y=-16
<u>-x+4y=24 +</u>
2x+0y=8
2x=8
divide by 2
x=4
sub back
-x+4y=24
-4+4y=24
add 4 both sides
4y=28
divide by 4
y=7
(x,y)
(4,7)
3.
add them to eliminate y's
-5x+3y=12
<u>-2x-3y=-33 +</u>
-7x+0y=-21
-7x=-21
divide both sides by -7
x=3
sub back
-2x-3y=-33
-6-3y=-33
add 6 to both sides
-3y=-27
divide both sides by -3
y=9
(x,y)
(3,9)
1. (4,7)
3. (3,9)
Answer:
The truck driver travels 2310 miles every day
Step-by-step explanation:
To make this more understandable (maybe not more simpler but still works lol) we will add 385 onto itself until we have done it 6 times
385 (1) + 385 (2) = 770
770 + 385 (3) = 1155
1155 + 385 (4) = 1540
1540 + 385 (5) = 1925
1925 + 385 (6) = 2310
