When dividing fractions, theres this thing you do call "keep, change, flip"
You keep the first fraction the same, change the division to a multiplication, and change the fraction to have the numbers flipped.
4 = 4/1
1 1/8 = 9/8
4/1 * 8/9 = 32/9
32/9 = 3 5/9
3 5/9 is the final answer
-4.5 + 4.2 + 5.6 - 7.3= -2.000000000000001−4.5+4.2+5.6−7.3=−2.000000000000001
Answer:

Step-by-step explanation:
As long as the two equations represent the same straight line on the coordinate plane (they overlap), there will be infinite many intersections and infinite number of solutions.
