Answer:
3x-2y=17........(1)
x=4y-1
substituting value of x in equation 1
3(4y-1)-2y=17
12y-3-2y=17
10y=17+3
y=20/10=2
again
substituting value of y in equation 1
3x-2×2=17
3x=17+4
x=21/3=7
:.x=7,y=2
I would say
Balanced forces result in constant velocity: phase 3
Unbalanced force causes change in velocity: phase 4
The more unbalanced the forces are, the greater the changes in velocity is: phase 5
Hope this helps
