Question

1) (y+476)-775=0; 2) (738+114)-(514+y)=0;
1) 250-(105-(36+a))=245; 2) (127-y)÷4=24; 3) (y -117)×11=121

Answer 1

1) (y+476)-775=0     у+476-775=0    у-229=0    у=299
2) (738+114)-(514+y)=0    852-514-у=0     338-у=0 -у=-338   у=338

1) 250-(105-(36+a))=245    250-(105-36-а)=245   250-69+а=245   181+а=245 а=64
2) (127-y)÷4=24   127-у=96   -у=96-127   -у=-31   у=31
3) (y -117)×11=121   у-117=121/11   у-117=11   у=128
