Question

6х-4=х+16 7х+8=4х+23 5(2х-6)=4х+18 2(3х+18)=4х+64 ПОМОГИТЕ С РЕШЕНИЕМ)

Answer 1

1)  6x-4=x+16 => 6x-x=16+4 => 5x=20 => x=20/5=4

2) 7х+8=4х+23 => 7x-4x = 23-8  => 3x = 15 => x=15/5=3

3) 5(2х-6)=4х+18 => 10x-5*6 = 4x+18  => 10x-4x = 18+30 => x=48/6=8

4) 2(3х+18)=4х+64 => 6x+36=4x+64 => 6x-2x = 64-36 => 2x = 28 => x=28/2=14
