Question

(x+2)/4-(x-1)/3=7 resolver esta ecuacion

Answer 1

$\frac{x+2}{4} - \frac{x-1}{3} = 7 \\ \\ \frac{3(x+2)}{12} - \frac{4(x-1)}{12} = 7 \\ \\ \frac{(3x + 6)-(4x-4)}{12} = 7 \\ \\ 3x + 6 - 4x + 4 = 7 *12 \\ \\ -x +10 = 84 \\ \\ -x = 84 -10 \\ \\ -x = 74 \\ \\ \boxed{x = - 74 }$

Espero que te sirva, salu2!!!!
