-12*(3х-4)=2*(-3+3)

4*(-5+3х)=-3*(-6х+1)

-9*(-3-4х)=-12*(-2х+3)



-8*(3х-3)=2*(-4х+2)

Answer 1

4*(-5+3х)=-3*(-6х+1)
-20+12х=18х-3
12х-18х=20-3
-6х=17
х=17:(-6)
х=-2 5/6

-9*(-3-4х)=-12*(-2х+3)
27+36х=24х-36
36х-24х=-36-27
12х=-63
х=-63:12
х=-5,25

-8*(3х-3)=2*(-4х+2)
-24х+24=-8х+4
-24х+8х=4-24
-16х=-20
х=-20:(-16)
х=1.25
