Equation step-by-step:

7d + 34 = 4d + 19

7d = 4d + 19 - 34 → we take 34 to the right side of the equation

7d = 4d -15 → we solve for 19 - 34

7d - 4d = -15 → we take 4d to the left side of the equation

3d = -15 → we solve for 7d - 4d

d = -15 / 3 → we take 3 to the right side of the equation

d = -5 → we solve for -15 / 3

The answer to the equation is d=-5.

You can begin to solve this by subtracting 4d from both sides to get the variable d one side of the equation.

7d+34=4d+19

7d-4d+34=4d-4d+19

3d+34=19

Now subtract 34 from both sides to isolate the variable d.

3d+34-34=19-34

3d=-15

Divide both sides by 3.


(3d)/(3)=
(-15)/(3)

d=-5
