Solve each equation for d when c = 0 10c+ 4d = 40

Hello!

The answer would be d = 10. Solve it like this. (v v v)

10 * 0 + 4 * d = 40 ---> 0 + 4 * 10 = 40

0 + 40 = 40

40 = 40

Hope this helps! ☺♥

 " d = 10 " .

Explanation:

Given:  " 10c + 4d =40"  ;  Solve for "d" ; when:  "c = 0" ;

Plug in "0" for "c" ; and simplify:

  10(0) + 4d = 40 ;

    0 + 4d = 40 ; 

          4d = 40 ;

Divide each side of the equation by "4";  to isolate "d" on one side of the equation; & to solve for "d" ;

    4d / 4  = 40 / 4 ; 

to get:

       
        d = 10 .
