Question

реши уравнения: (x-30)+26=75 , 34*x-16=52

Answer 1

(x-30)+26=75
x - 30 + 26 = 75
x - 4 = 75
x = 75 + 4
x = 79

34*x-16=52
34x = 52 + 16
34x = 68
x = 68 : 34
x = 2

Answer 2

$(x - 30) + 26 = 75 \ x - 30 + 26 = 75 \ x - 4 = 75 \ x = 75 + 4 \ x = 79.$
$34x - 16 = 52 \ 34x = 52 + 16 \ 34x = 68 \ x = frac{68}{34} \ x = 2.$
Удачи, учись хорошо :)
