Question

a) 83x - 67x = 384;
б) 32x + 14x27x+5 = 100;
B) (17x-8x + 3): 7 = 12.
a) 708 + 139x + 24 + 341x= = 1692;
б) 3(7+4x)- 8x = 201;
B) 770: (4x + 18x) - 12 = 23.​

Answer 1

1) 83x-67x=384
16x=384
x=384:16=24
2) 32x+14x-27x+5=100
19x=100-5=95
x=95:19=5
3) (17x-8x+3):17=12
(17x-8x+3):7=12
17x-8x+3=12•7
9x=84-3
9x=81
x=81:9
x=9
4) 708 + 139x + 24 + 341x=1692
139х+341х= 1692-708-24
480х=960
х= 960:480
х=2
5) 3(7 + 4x) - 8x = 201
21+12х-8х=201
12х-8х=201-21
4х=180
х=180:4
х=45
6)770 : (4х + 18 х ) - 12 = 23
770:(22х)=23+12
35•22X=770
770х=770
х=770:770
х=1
