Resposta:

$a)\\ \\ 8x-3y+15x+22y=8x+15x+22y-3y=23x+19y\\ \\ b)\\ \\ a+b-14a-16b=a-14a+b-16b=-13a-15b$

$c)\\ \\ -13+mn-3m+8n+5mn-10m+26=\\ \\ mn+5mn-3m-10m+8n-13+26=\\ \\ 6mn-13m+8n+13\\ \\ d)\\ \\ -23c+42d-22d+11c=\\ \\ -23c+11c+42d-22d=\\ \\ -12c+20d$

$e)\\ \\ x^{2} +xy+2x^{2} -32xy=\\ \\ x^{2} +2x^{2} +xy-32xy=\\ \\ 3x^{2} -31xy\\ \\ f)\\ \\ 3y-\frac{1}{3} y+2=\\ \\ \frac{9y-y}{3} +2=\\ \\ \frac{8y}{3} +2=\\ \\ \frac{8y+6}{3}$
