Question

475-(х-671)=325
972-(у-504)=284
403-(634-а)=366
643-(581-b)=292
987-(x+364)=519
3127-(m+425)=1509

Answer 1

475-(х-671)=325
475-x+671=325
-x=325-475-671
-x=-821
x= 821

972-(у-504)=284
972-y+504=284
-y= 284-504-972
-y=-1192
y=1192

403-(634-а)=366
403-634+a=366
a=366-403+634
a=327

643-(581-b)=292
643-581+b=292
b=292-643+581
b= 230

987-(x+364)=519
987-x-364=519
-x=519-987+364
-x= -104
x= 104

3127-(m+425)=1509
3127-m-425=1509
-m=1509+425-3127
-m=-1193
m=1193
