Linear+Equations+3

Model and solve problems, using linear equations of the form:

//ax=b// • //x//=//b//,//a//≠0 //a// • //ax+b=c// • //ax//+//b//=//c,a//≠0 • //ax=b+cx// • //a(x+b)=c// • //ax+b=cx+d// • //a(bx+c)=d(ex+f)// • //ax// = //b, x// ≠ 0

where //a//, //b, c, d, e// and //f// are rational numbers.
