2(3x-7)=- 3(2x-5) -2(2x+5)+(3x+17)-(8x+5)=15

Question

2(3x-7)=- 3(2x-5) -2(2x+5)+(3x+17)-(8x+5)=15

Answer 1

2(3x-7)=- 3(2x-5)

6х-14=-6х+15

6х+6х=14+15

12х=29

х=29/12

х=2 5/12                                              

 

-2(2x+5)+(3x+17)-(8x+5)=15

-4х-10+3х+17-8х-5=15

-4х+3х-8х=15-17+10+5

-9х=13

х=-13/9

х=-1 4/9
