Question

9х-6(-2+х)=-7*5х+20-3(6х+2)-1=4(х-3)-9-5(-5+3х)-1=9х+5*6

Answer 1

-3(6х+2)-1=4(х-3)-9
-18х - 6 - 1 = 4х - 12 - 9
-18х - 4х = -12 - 9 + 6 + 1
-22х = -14
22х = 14
х = 14 : 22
х = 7/11

-5(-5+3х)-1=9х+5*6
25 - 15х - 1 = 9х + 30
-15х - 9х = 30 - 25 + 1
-24х = 6
24х = -6
х = -6 : 24
х = -0,25
