Question

REALIZA:

a) 6+8.x igual 10.x-9:





b)24.x-1 igual 48.x+3:






c)3.x igual 27:





d) 2.(3x-1) igual 3(x+2):






e)9x-5 igual 4x+10:

Answer 1

Respuesta:

$a)6 + 8x = 10x - 9 \\ 8x - 10x = - 9 - 6 \\ - 2x = - 15 \\ x = \frac{15}{2} \\ \\ b)24x - 1 = 48x + 3 \\ 24x - 48x = 3 + 1 \\ - 24x = 4 \\ x = - \frac{4}{24} \\ x = - \frac{1}{6}$

Explicación paso a paso:

$c)3x = 27 \\ x = 27 \div 3 \\ x = 9 \\ \\ d)2(3x - 1) = 3(x + 2) \\ 6x - 2 = 3x + 6 \\ 6x - 3x = 6 + 2 \\ 3x = 8 \\ x = \frac{8}{3} \\ \\ e)9x - 5 = 4x + 10 \\ 9x - 4x = 10 + 5 \\ 5x = 15 \\ x = 15 \div 5 \\ x = 3$
