Ренения уровнения —8х+(4+3х)=10-х 5-2х=11-7(х+2)

Question

Ренения уровнения —8х+(4+3х)=10-х 5-2х=11-7(х+2)

Answer 1

1) - 8x + (4 + 3x) = 10 - x
- 8x + 4 + 3x = 10 - x
- 8x + 3x + x = 10 - 4
- 4x = 6
x = - 1,5
2) 5 - 2x = 11 - 7(x + 2)
5 - 2x = 11 - 7x - 14
- 2x + 7x = 11 - 14 - 5
5x = - 8
x = - 1,6
