Question

(999x+999)-(742+581x)=(1+1)2x-(-83+320x)


alguém me ajudaaaa​

Answer 1

$(999x + 999) - (742 + 581x) = (1 + 1) \times 2x - ( - 83 + 320x)$

$999x + 999 - 742 - 581x = 2 \times 2x + 83 - 320x$

$418x + 257 = 4x + 8x - 320x$

$418x + 257 = - 316x + 83$

$734x = - 174$

$x = - \frac{174}{734}$

$x = - \frac{87}{367} = - 0.237057$
