Question

por favor es para yaaaaaaa doy coronita ¡¡¡¡¡¡¡¡¡¡¡
[tex]\frac{4x + 1 }{13} = \frac{5x -3}{4}[/tex]
[tex]-3 (5x-2)= -4 (-3-4 )[/tex]

Answer 1

Verified answer

Explicación paso a paso:

[tex]\frac{4x + 1 }{13} = \frac{5x -3}{4} \\ (4x + 1) \times 4 = (5x - 3) \times 13 \\ 16x + 4 = 65x - 39 \\ 4 + 39 = 65x - 16x \\ 43 = 49x \\ \frac{43}{49} = x[/tex]

El segundo:

[tex]-3 (5x-2)= -4 (-3-4) \\ - 15x + 6 = - 4 \times ( - 7) \\ - 15x = 28 - 6 \\ x = 22 \div ( - 15) \\ x = \frac{ - 22}{15} [/tex]
