Question

Solve 10 - 3x = 2x - 8x + 20

Answer 1

$10 - 3x = 2x - 8x + 20\\ 3x=10\\ x=\frac{10}{3}$

Answer 2

$10-3x=2x-8x+20\\\\10-3x=-6x+20\ \ \ \ |subtract\ 10\ from\ both\ sides\\\\-3x=-6x+10\ \ \ \ |add\ 6x\ to\ both\ sides\\\\3x=10\ \ \ \ \ |divide\ both\ sides\ by\ 3\\\\x=\frac{10}{3}\\\\\boxed{x=3\frac{1}{3}}$
