Answer 1

Step-by-step explanation:

−20

−204

−2042+7+6+x

−2042+7+6+x

−2042+7+6+x =15

−2042+7+6+x =1515+x=60

−2042+7+6+x =1515+x=60x=45

−2042+7+6+x =1515+x=60x=45Now,

−2042+7+6+x =1515+x=60x=45Now,5

−2042+7+6+x =1515+x=60x=45Now,518+1+6+45+y

−2042+7+6+x =1515+x=60x=45Now,518+1+6+45+y

−2042+7+6+x =1515+x=60x=45Now,518+1+6+45+y =10

−2042+7+6+x =1515+x=60x=45Now,518+1+6+45+y =1070+y=50

−2042+7+6+x =1515+x=60x=45Now,518+1+6+45+y =1070+y=50y=−20
