Question

(3) - 2x + 3 = 7
(6) 16- X/3 = 15​

Answer 1

$\huge\bf{Answer :}$

(i)

Given :

$- 2x + 3 = 7$

Solution :

$- 2x + 3 = 7 \: \: \: \: \: \: \: \: \: \: \: \: \\ \: \: \: \: - 2x = 7 - 3 \\ - 2x = 4 \: \: \: \: \\ - x = \frac{4}{2} \\ \: \: \: \: \: \: x = - 2$

$\huge\bf{x = -2}$

(ii)

Given :

$16 - \frac{x}{3} = 15$

Solution :

$16 - \frac{x}{3} = 15 \\ \frac{48 - x}{3} = 15 \\ 48 - x = 15 \times 3 \\ 48 - x = 45 \\ x = 48 - 45 \\ x = 3$

$\huge\bf{x = 3}$

$\huge{Thanks}$

Answer 2

Step-by-step explanati

-2x + 3 = 7

-2x = 7 - 3

-2x = 4

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

x = $\frac{2}{ - 1}$
