¾ + 2a = ½

nilai a = ...

XxDarknessxX

¾ + 2a = ½

2a = ½ - ¾

2a = 1×2/2×2 - ¾

2a = 2/4 - 3/4

2a = 2-3/4

2a = -1/4

a = 2 ÷ -1/4

a = 2 × 4/-1

a = 2 × -4

a = -8

~ Persamaan

$\frac{3}{4} + 2a = \frac{1}{2}$

$2a = \frac{1}{2} - \frac{3}{4}$

$2a = \frac{1 \times 2}{2 \times 2} - \frac{3}{4}$

$2a = \frac{2}{4} - \frac{3}{4}$

$2a = \frac{2 - 3}{4}$

$2a = - \frac{1}{4}$

$a = - \frac{1}{4} \div 2$

$a = - \frac{1}{8}$

Jadi, nilai a yg memenuhi bntk persamaan tsb adalah -⅛
