Question 12

The equation having 5 as a solution is

(a) 4x + 1 = 2

(b) 3 - x = 8

(c) x - 5 = 3

(d) 3 + x = 8

Answer 1

Let us solve the equations:
(a) Given equation is 4x + 1 = 2
$\Rightarrow 4x=2-1\Rightarrow 4x=1\Rightarrow x=\frac{1}{4}$
(b) Given equation is 3 - x = 8
$\Rightarrow -x=8-3\Rightarrow -x=5\Rightarrow x=-5$
(c) Given equation is x - 5 = 3
$\Rightarrow x=3+5\Rightarrow x=8$
(d) Given equation is 3 + x = 8
$\Rightarrow x=8-3\Rightarrow x=5$
