Решить уравнения 6-5x=2x+15 2(x+1)=3 -5(3-x)-2+7 3(10-7x)-x=-3

6-5х=2х+15
-5х - 2х = 15 - 6
 -7х = 9
х = -9/7 = - 1  2/7

2(x+1) = 3
2x + 2 = 3
2x = 1
x = 1/2 = 0,5

-5(3-x) - 2 = 7
-15 + 5x - 2 = 7
5x - 24
x = 24/5 = 4  4/5

3(10 - 7x) - x = -3
30 - 21x - x = -3
-22x = -3-30
-22x = -33
x = 33/22 = 3/2
