Answer»

Solve the equations:



(i) 5x = 3x + 24;



(ii) 8t + 5 = 2t − 31;



(iii) 7x − 10 = 4x + 11;



(iv) 4z + 3 = 6 + 2z;



(v) 2x − 1 = 14 − x;



(vi) 6x + 1 = 3(x − 1) + 7;



(vii) ;



(viii) ;



(ix) 3(x + 1) = 12 + 4 (x − 1);



(x) 2x − 5 = 3(x − 5);



(xi) 6(1 − 4x) + 7(2 + 5x) = 53;



(xii) 3(x + 6) + 2 (x + 3) = 64;



(xiii) ;



(xiv) .
