Penjelasan dengan langkah-langkah:

a. 2/4

= 2/4 ÷ 2/2

= 1/2

= – 2(7) – 9

= -14 – 9

= -14 + (-9

= -23

2x + 3 = 4 – x

2x + x = 4 – 3

3x = 1

x = 1/3

$sf bf tt frac{2}{4}$

$sf bf tt frac{2 ÷ 2}{4 ÷ 2}$

$sf bf tt frac{1}{2}$

$sf bf tt - 2(7) - 9$

$sf bf tt -14- 9$

$sf bf tt -(14+9)$

$bold{underline{boxed{pink{sf bf tt (-25)}}}}$

$sf bf tt 2x + 3 = 4 - x$

$sf bf tt 2x - x = 4-3$

$bold{underline{boxed{pink{sf bf tt x = 1}}}}$
