Hp dari 2/5 (x-9) = 1/4 (3x+5) adalah

2(x-9)/5 = 1(3x+5)/4
2x-18/5 = 3x+5/4

(2x-18)4 = (3x+5)5
8x-72 = 15x+25
8x -15x = 25 + 72
-7x = 97
x = 97/-7

Hp : { ( x = -97/7 ) }

[tex] \frac{2}{5}(x-9)= \frac{1}{4} (3x + 5)\\ \frac{2(x-9)}{5} = \frac{3x+5}{4} \\ 4\times 2(x - 9) = 5 \times(3x + 5)\\ 8(x - 9) = 15x +25\\ 8x - 72 =15x + 25\\ 8x - 15x = 25 + 72\\ -7x = 97\\ x = 97\div(-7)\\ \bold{x = -13 \frac{6}{7} }[/tex]

HP = {[tex]x = -13 \frac{6}{7}[/tex]}
