sorry i cant help u
for example:2x + 3 = x + 3
2x - x = 3-3 , = x = o
all the questions are based on this example........
can u help littlerose...........

1) v² = u² + 2 fs
2 fs = v² - u²
s = (v² - u²)/2 f

2) s = n/2{2a + (n - 1)d}
2s/n = 2a+ (n - 1)d
2s/n - 2a = (n - 1)d
(2s - 2an)/n = (n - 1)/d
(2s - 2an)/n(n-1) = d
d = (2s - 2an) / (n² - n)

3)
p = a - m/a + m
p - a = m - m/a
p - a = m(1 - 1/a)
p - a = m((a - 1)/a)
p - a = m(a - 1)/a
a(p - a) = m(a - 1)
(ap - a²)/(a-1) = m
m = (ap - a²) / (a - 1)

4)
1/f = 1/v - 1/u
1/f + 1/u = 1/v
(u+f)/fu = 1/v
RECIPROCAL ON BOTH SIDES.
fu/(u+f) = v
v = fu / (u+f)
