Hi there!
Th' Eqn. is :-
4 (x - 3) = 2 (3x + 1)
=> 4x - 12 = 2 (3x + 1)
=> 4x - 12 = 6x + 2
Combine th' like terms :-
=> 4x - 6x = 2 + 12
=> - 2x = 14
=> x =

=> x = - 7
Hence, The required answer is : x = - 7
~ Hope it helps!
The first one. 1 machine= x 5 mach.=5x. Total time is thus 5x+2/3=1 3/4h. Simply find x by doing 105min-40min/5 and that is 13.
Answer:
The correct option is B.
Step-by-step explanation:
If polar coordinates of point P are

Where, r is real number and θ is in radian, then all polar coordinates of point P are defined as


The given coordinates are
. So, all polar coordinates of point P are


Therefore correct option is B.
