Question

4(2х-1)+3(1-2х)=7
4(х+2)-2(3х-2)=14х-5(х+3)
Помогите пожалуйста!​

Answer 1

$4(2x - 1) + 3(1 - 2x) = 7 \ 8x - 4 + 3 - 6x = 7 \ 2x = 7 + 1 \ 2x = 8 \ x = 8 div 2 \ x = 4$

$4(x + 2) - 2(3x - 2) = 14x - 5(x + 3) \ 4x + 8 - 6x + 4 = 14x - 5x - 15 \ - 2x + 12 = 9x- 15 \ - 2x - 9x = - 15 - 12 \ - 11x = - 27 \ x = frac{ - 27}{ - 11} \ x = 2 frac{5}{11}$
