Question

4*(Х-97)=68                                120:(35-х)=20                     940-2*а=0         620:(с+24)=10

Answer 1

4x-338=68

4x=338+68

4x=456

 

(35-x)=120-20.

(35-x)=100.

35-x=100

x=35:100

x=0.35.

 

940-2a=0

-2a=-940

a=(-2):(-940)

a=470

 

620:(c+24)=10

(c+24)=-620+10

(c+24)=-610

c+24=-610

c=-610-24

c=634
