Question

1.5х+7=10 2.6а-0.9=3 б:10-0.1=0.07

Answer 1

1,5х+7=10

1,5х=10-7

х=3:1,5

х=2

2,6а-0,9=3

2.6а=3+0.9

а=3.9:2.6

а=1.5

б:10-0.1=0.07

б:10=0.07+0.1

б=0.17х10

б=1.7

Answer 2

 2) 2.6a-0.9=3        3)b/10-0.1=0.07

     2.6a=3+0.9             b/10=0.07+0.1

     a=3.9/2.6                b=0.17x+10    

     a=1.5                      b=1.7   

 

 

 

 

 1)1.5+7=10

1.5x=10-7

x=3/1.5
