Question

let g = 5.9d - 4.2

 

Now write a formula that gives d in terms of g

 

 

Answer 1

you just want to solve for the value of the variable "d" algebraically! that means taking

g = 5.9d - 4.2

g + 4.2 = 5.9d

d = (g + 4.2)/5.9

Answer 2

You need to solve for d.  Add 4.2 to both sides of the equation.

 

g + 4.2 = 5.9d

 

 

Then divide both sides of the equation by 5.9.

 

(g + 4.2) / 5.9 = d
