Resover cada ecuacion x = 5x - 13 9x - 4 = 2x x + 5x = - 10 + 3 4x - 5x - 9 = 3x + 4x 4x - 9x + 2 = 7x - 5x - 9 3x - 8x + 9x = 12 - 7x ayuda urgente.
ax² + bx + c = 0
En resumen
1)× - 5× = - 13 - 4× = - 13 / * - 1 4× = 13 × = 13÷4 × = 3. 25 2) 9× - 2× = 4 7× = 4 × = 4÷7 × = 0. 57 3) 6× = - 7 × = - 7÷6 x = - 1. 16667 4) 4× - 5× - 3× - 4× = 9 - 8× = 9 / * - 1 × = 9÷8 × = 1. 125.
1)× - 5× = - 13 - 4× = - 13 / * - 1 4× = 13 × = 13÷4 × = 3.
25
2) 9× - 2× = 4 7× = 4 × = 4÷7 × = 0.
57
3) 6× = - 7 × = - 7÷6 x = - 1.
16667
4) 4× - 5× - 3× - 4× = 9 - 8× = 9 / * - 1 × = 9÷8
× = 1.
125.
