Weegy: 6(x - 2) = 4

6x - 12 = 4;

6x = 4 + 12;

6x = 16;

x = 16/6;

x = 8/3

6x = 16;

x = 16/6;

x = 8/3



User: (2x - y)(4x2 + 2xy + y2)

Weegy: SOLUTION 13 : Begin with x2 + xy + y2 = 1 . .... y = 2x . Substituting this into the original equation x2 - xy + y2 = 3 leads to. x2 - x (2x) + (2x)2 ... x2 - 2x2 + 4x2 = 3 ,.
