REZOLVATI IN R URMATOARELE ECUATII

a) 2(x+1)-5(3x+5)=-2x-5

Answer 1

[tex]2(x+1)-5(3x+5)=-2x-5 \\ 2x+2-15x-25=-2x-5 \\ -13x-23=-2x-5|*(-1) \\ 13x+23=2x+5 \\ 11x=-18 \\ \boxed{x=- \frac{18}{11}} [/tex]

Answer 2

$2(x+1)-5(3x+5)=-2x-5$
$<=>2x+2-15x-25=-2x-5$
$<=>2x-15x+2x+2-25+5=0$
$<=> -11x-18=0$
$<=>-11x=18$
$x=- \frac{18}{11}$
