Question

помогите решить уравнение x+2-4(x-2)=5(3-x)+3

Answer 1

х + 2 - 4 * ( х - 2) = 5 * (3 - х) + 3

х + 2 - 4х + 8 = 15 - 5х + 3

х - 4х + 5х = 15 + 3 - 2 - 8

2х = 8

х = 8 : 2

х = 4

Проверка: 4 + 2 - 4(4 - 2) = 5(3 - 4) + 3

                   6 - 4 * 2 = 5 * (-1) + 3

                   6 - 8 = - 5 + 3

                   - 2 = - 2

Answer 2

-9(8-9x)=4x+5

Answer 3

81х - 4х = 5 + 72

Answer 4

77х = 77

Answer 5

х = 77 : 77 х = 1
