Answer:
Step-by-step explanation:
Two lines are parallel if they have the same slope. Two parallel lines never intersect.
While you cannot solve 946x+642y=911 for numerical values of x and y, you can indeed solve 946x+642y=911 first for x and then for y:
-911 - 642y
For x: 946x+642y=911 becomes 946x = 911 - 642y, or x = ------------------
946
911-946x
For y: 946x+642y=911 becomes 642y = 911-946x, or y = ---------------
642
Answer:
Step-by-step explanation:
el número es 4,5
es una ecuación lineal:
2x+18=27
2x=9
x=9/2
x=4,5
