Answer 1

n-567=134
n=567+134
n=701
proba 701-567=134

y+206=306
y=306-206
y=100
proba100+206=306

m+39=420
m=420-39
m=381
proba 381+39=420


a+328=500
a=500-328
a=172
proba 172+328=500


231-b=45
b=231-45
b=186
proba 231-186=45

800-t=450
t=800-450
t=350
proba 800-350=450


y+135=276
y=276-135
y=141
proba 141+135=276


x-206=306
x=306+206
x=512
proba512-206=306
