Question

Решите уравнения
1) 6х+8х-7х=714
2) 23х-19х+5х=1827

Answer 1

1) 6x + 8x - 7x = 714;

x(6 + 8 - 7) = 714;

7x = 714;


x = 714 : 7;

x = 102.

2) 23x - 19x + 5x = 1827;

x(23 - 19 + 5) = 1827;

9x = 1827;

x = 1827 : 9;

x = 203.

Answer 2

$6x + 8x - 7x = 714 \\ 7x = 714 \\ x = 12 \\ \\ 23x - 19x + 5x = 1827 \\ 9x = 1827 \\ x =203$
