Question

Resolva a equação 2X+3 =
= ¼​

Answer 1

$2x+3=\frac{1}{4} \\\\4(2x+3)=4(\frac{1}{4})\:\: [multiplicamos \:ambos \:os\:lados\: da\: igualdade \:por\: 4] \\\\\ 8x+12=1\\\\8x+12-12=1-12 \:[subtraimos\:12 \:de\:cada\:lado]\\\\8x=-11\\\\\frac{8x}{8} =\frac{-11}{8} \:[dividimos \:ambos \:os\: lados\: por\: 8]\\\\x=\frac{-11}{8}$
