Question

Exercise 16.2
1. Make x the subject of the following
relations:
a) 2y+3 = 5x-18
b) ry + 2x = tx +4
c) kx + 6y = 4x - 3y
d) m+n+ex = 2m - x
e) 7x+u = vu​

Answer 1

A) Answer:

$x = \frac{2y + 21}{5}$

B) Answer:

$x = \frac{4 - ry}{2 - t}$

C) Answer:

$x = \frac{9y}{4 - k}$

D) Answer:

This equation has no solution for X. but for n the answer would be,

$n = m - x - ex$

E) Answer:

$x = \frac{u(v - 1)}{7}$
