Question

( x + 7 )\3 + x\2 ≈ x + 1

Answer 1

(x + 7)/3 + x/2 = x + 1
(2x + 14 + 3x)/6 = x + 1
2x + 14 + 3x/6 = x + 1
2x + 14 + 3x = 6x + 6
14 - 6 = 6x - 3x - 2x
8 = x

Answer 2

( x + 7 )\3 + x\2 ≈ x + 1
( x + 7 ) + x ≈ x + 1                 mmc = 6     3         2

2( x + 7 ) + 3x ≈ 6(x + 1) ==> 2x + 14 + 3x ≈ 6x + 6

6x - 3x - 2x = - 6 + 14 ==> x = 8
