Answer:
The answer to number seven is 420 km.
Answer:
2
(
y
2
+
17
)
Step-by-step explanation:
3x³ + x + 2x³ - 4x² - 2(y + x)
3x³ + 2x³ - 4x² + x - 2(y) - 2(x)
5x³ - 4x² + x - 2y - 2x
5x³ - 4x² + x - 2x - 2y
5x³ - 4x² - x - 2y
Answer:
Hey there!
3x+y=7
2x+y=6
3x+y=7
-2x-y=-6
Add these two equations vertically so the y terms cancel out (this is known as the elimination method)
x=1
3x+y=7
3(1)+y=7
3+y=7
y=4
(x=1, y=4)
Hope this helps :)
