Question

Как решить 5(1-x)+8x=-2-(2x+3)

Answer 1

5(1-х) + 8х =  -2 -(2х+3)
5*1 - 5*х  +8х = -2 -2х -3
5 +3х = -5-2х
3х+2х=-5 -5
5х= -10
х= (-10) :  5
х = -2
проверим:
5( 1 - (-2))  + 8 *(-2) = -2 - (2 * (-2) + 3)
5(1+2)  - 16 = -2 - (-4+3)
15 -16 = -2 -(-1)
-1 = -2+1
-1 = -1

Answer 2

5(1-х)+8х=-2-(2х+3)
5-5х+8х=-2+2х-3
-5х+8х-2х=-2-3-5
х=-10
