make the letter in the bracket the subject of the formulae:
v=u-3t (t)
a=b-4c (c)
make v the subject of the formulae:
v=2v+3u
Rearrange the equaqtion as follows.
3t = u-v
t = (u - v)/3
Do the other the same way.
Nabby's advice and equation are wrong.
i meant V=2v+3u
make the small v the subject of the formulae
It is confusing if you change your name and add additional questions to the same thread. Your questions then look like attempted answers. Start a new question. Uing both upper and lower case of the same letter in an equation is not advised in algebra, although physicists have to do it quite often.
To make the letter in the bracket the subject of the formulas, we need to rearrange the equations to isolate the specified variable.
1. Given formula: v = u - 3t
To make "t" the subject, we need to isolate "t" on one side of the equation.
Start by subtracting "u" from both sides:
v - u = -3t
Divide both sides by -3:
(v - u) / -3 = t
Therefore, the rearranged formula with "t" as the subject is:
t = (u - v) / 3
2. Given formula: a = b - 4c
To make "c" the subject, we'll follow the same steps.
Start by subtracting "b" from both sides:
a - b = -4c
Divide both sides by -4:
(a - b) / -4 = c
Therefore, the rearranged formula with "c" as the subject is:
c = (b - a) / 4
Now, you have the formulas where "t" and "c" are the subjects of the respective equations.
