Question

87-6=95-х
78/2+9=
(85-74)-х=101

Answer 1

Ответ:

87-6=95-x

81=95-x

x=95-81

x=14

$\frac{78}{2} + 9 = 48$

(85-74)-x=101

11-x=101

-x=101-11

x=-90

Answer 2

Ответ:

$87 - 6 = 95 - x \\ 81 = 95 - x \\ x = 95 - 81 \\ x = 14$

-------------

$\frac{78}{2} + 9 = \frac{78 \div 2}{2 \div 2} + 9 = 39 + 9 = 48$

-------------

$(85 - 74) - x = 101 \\ 11 - x = 101 \\ - x = 101 - 11 \\ - x = 90 \\ x = - 90$
