Question

rezolvati in Q+: a) 2(2/3 x-1)-1/2= x/6

Answer 1

$= (2 \div 3 )\times( 2x - 3) - 3 \div 6 = \\ x \div 6 \\ 4 \div 6 \times (2x - 3) - 3 \div 6 = x \div 6 \\ 8x - 12 - 3 = x \\ 8x - 15 = x \\ \ \\ 7x = 15 = > x = 15 \div 7 = > x = 2.14...$

Answer 2

2(2/3x-1)-1/2=x/6=
Se inversează factorii
[2(2/36-1)-1]/2=x/x
[2(18-1)-1]/2=x
(2*17-1)/2=x
(34-1)/2=x
33/2=x
16.5=x
