Question

Rezolvati escuatia : 63+{9*[18+(2x-4):2]}*3=576 cat este x?

Answer 1

63 + {9 * [18 + (2x - 4) : 2]} * 3 = 576
{9 * [18 + (2x - 4) : 2]} * 3 = 576 - 63
9 * [18 + (2x - 4) : 2] = 513 : 3
18 + (2x - 4) : 2 = 171 : 9
(2x - 4) : 2 =  19 - 18
2x - 4 = 1 * 2
2x = 2 + 4
x = 6 : 2
x = 3

Answer 2

63+{9x[18+(2X-4):2]}X3=576
{9x[18+(2X-4):2]}X3=576-63=513
{9x[18+(2X-4):2]}=513:3=171
[18+(2X-4):2]=171:9=19
18+(2X-4):2=19
(2X-4):2=19-18=1
2X-4=1x2=2
2X-4=2
2X=2+4
2X=6
X=6:2
X=3
