Question

5(8x-1)-2x = 40x+ 3 POR FAVOR ..

Answer 1

Respuesta:

x = -4

Explicación paso a paso:

5(8x - 1) - 2x = 40x + 3

40x - 5 - 2x = 40x + 3

40x - 2x - 40x = 3 + 5

-2x = 8

x = -4

Comprobación:

5(8x - 1) - 2x = 40x + 3

5[8(-4) - 1] - 2(-4) = 40(-4) + 3

5(-32 - 1) - (-8) = -160 + 3

5(-33) + 8 = -147

-165 + 8 = -147

-147 = -147
