Question

Помогите решить пожалуйста 14 2/13 - ( x + 7 19/39 ) = 1 3/78

Answer 1

14 2/13-(х+7 19/39)=1 3/78
14 2/13-х-7 19/39=1 3/78
-х=1 3/78+7 19/39-14 2/13
-х=-5 49/78
х=5 49/78


* 1 3/78+7 38/78-14 12/78=8 41/78-
14 12/78=-5 49/78

Answer 2

14 2/13 - ( x + 7 19/39 ) = 1 3/78
x+7 19/39=1 3/78-14 2/13
x+7 19/39= -13 9/78
x=-13 9/78÷(-7 19/39)
x=1 439/584
