Question

4. Решите уравнение: 1) (58 + x) – 23 = 96 2) 54 – (x – 19) = 35.

Answer 1

1)(58 + x) – 23 = 96
58-23+x=96
35+x=96
x=96-35
x=61
2)54 – (x – 19) = 35.
54-x+19=35
-x+73=35
-x=35-73
x=73-35
x=38

Answer 2

1) (58+х)-23= 96
58+х= 96 + 23
58+х= 89
х=89-58
х=31


2)54-(х-19)=35
х-19=54-35
х-19= 19
х=19+19
х=38
