Question

Решите примеры

3(х+3)-3(4-х)-х-3

3(х+5)-(4-х)-(4-х)-(1+3)х-3

2(х+4)-3(2-х)-х-4

Х+1-5(2-х)-(5+1)х-5

Х+3-(2-х)-х-4

Answer 1

3(х+3)-3(4-х)-х-3=3х+9-12+3х-х-3=5х-6

3(х+5)-(4-х)-(4-х)-(1+3)х-3=3х+15-4+х-4+х-4х-3=х+8

2(х+4)-3(2-х)-х-4=2х+8-6+3х-х-4=4х-2

Х+1-5(2-х)-(5+1)х-5=х+1-10+5х-6х-5=-14

Х+3-(2-х)-х-4=х+3-2+х-х-4=х-3
