Question

1)(x + 7,9): 48-0,02=15,7 2)(х-56,3): 7-25,015=306,3

Answer 1

1) (x+7.9):48=15.7+0.02--->(x+7.9):48=15.72--> x+7.9=15.72*48--->x+7.9=754.56--->x=754.56-7.9=746.66
2)(x-56.3):7=331.315>x-56.3=2319.205--->x=2375.505

Answer 2

(x+7,9):48=15,72
x+7,9=15,72*48
x+7,9=754,56
x=754,56-7,9
x=746,66

(x-56,3):7=306,3+25,015
(x-56,3)=331,315*7
x=2319,205+56,3
x=2375,505
