Question

Помогите решить уравнения. 98x-87x=594 23x-12x+6x+5=90 (16x-10x+3)*4=132

Answer 1

1)98x-87x=594

11х=594

х=594:11

х=54

2)23x-12x+6x+5=90

17х+5=90

17х=90-5

17х=85

х=5

3)(16x-10x+3)*4=132

(6х+3)*4=132

24х+12=132

24х=132-12

24х=120

х=5

Answer 2

1.
98х-87х=594
11•х=594
Х=594:11
Х=54
2.
23х-12х+6х+5=90
17х+90-5
17•х=90-5
17•х=85
х=5
3.
(16х-10х+3)•4=132
(6х+3)•4=132
24•х+12=132
24•х=132-12
24•х=120
Х=120:24
Х=5
