Solve for y. show work. answer may be left as decimal. 0.4(y+10)+0.6y=2

Answer

-20

Step-by-step explanation:

0.4y + 0.06y = 0.10y

0.4 x 10 = 4

0.10y + 4 = 2

         -4     -4

0.10y/0.10 = -2/ 0.10 = -20

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
