Question

решите уравнение 12( х-3)=14(9- х)

Answer 1

1/2(х-3)=1/4(9-х)
1/2х-3/2=9/4-1/4х
2/4х+1/4х=9/4+6/4
3/4х=15/4
х=15/4:3/4
х=5

Answer 2

12 ( x -3 ) = 14 (9-x)
12x -32 = 94 -14x
12x + 14x = 94 + 32
12 x + 14x =24x + 14x =34x
94 + 32 =94 + 64 =154
34x = 154
x = 154 : 34
154 :34 = 154 x 43=5
x = 5
