Помогите решить уравнения 1)6x+18=0 2)2x+3=3x-2 3)3(5-x)=11+2x 4)3/4(4+8)=9(7x-1) 5)(7-10x)-(8-8x)+(10x+6)=-8

6x = - 18 x = - 18/6 x = - 3 2x - 3x = - 3 - 2 - x = -5 x =5 15 - 3x = 11 + 2x - 3x - 2x = - 15 + 11 - 5x = - 4 5x = 4 x = 4/5 x = 0,8 3 + 6 = 63x - 9 - 63x = - 9 - 9 - 63x = - 18 63x = 18 x= 18/63 x = 6/21 x = 2/7 7 - 10x - 8 + 8x + 10x + 6 = - 8 8x = - 8 - 5 8x = - 13 x = - 13/8 x = - 1,625
