Question

(X-3)-(3x-4)= 15 X/2+X/3=10 Ответы с решением.

Answer 1

(х-3)-(3х-4)=15
х-3-3х+4=15
-2х+1=15
-2х=15-1
-2х=14
х=14:(-2)
х=-7


$\frac{x}{2} + \frac{x}{3} = 10 \\ \\ 3x + 2x = 60 \\ \\ 5x = 60 \\ \\ x = 60 \div 5 \\ \\ x = 12$

Answer 2

(x-3)-(3x-4)=15
x-3-3x+4=15
-2x+1=15
-2x=14
x=-7

x/2+x/3=10
(3x+2x)/6=10
5x/6=10
5x=60
x=12
