A) R = ax/3 3R = ax x = 3R/a b) y = 2t - 3x 3x = 2t - y x = (2t - y)/3 c) y = 2 - 1/k 1/k = 2 - y 1 = k(2 - y) k = 1/(2 - y) d) y = 2(x - 1) y = 2x - 2 2x = y + 2 x = (y + 2)/2
R = ax/3
3R = ax
x = 3R/a
b)
y = 2t - 3x
3x = 2t - y
x = (2t - y)/3
c)
y = 2 - 1/k
1/k = 2 - y
1 = k(2 - y)
k = 1/(2 - y)
d)
y = 2(x - 1)
y = 2x - 2
2x = y + 2
x = (y + 2)/2
