3 1/2 (5×+1)-1 1/2 (5×+1)

Jawaban:

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

Penjelasan dengan langkah-langkah:

$3 times frac{1}{2}(5x + 1) - 1 times frac{1}{2}(5x + 1) \ = frac{7}{2} (5x + 1) - frac{3}{2} (5x + 1) \ = frac{35}{2} x + frac{7}{2} - frac{15}{2} x + frac{3}{2} \ = frac{20}{2} x + frac{10}{2} \ 10x = 5 \ x = - frac{1}{2}$
