What is the solution to the multi step equation 4d-2+3d=61? justify your steps. then check your solution.

d=9

Step-by-step explanation:

4d−2+3d=61

Step 1: Simplify both sides of the equation.

4d−2+3d=61

4d+−2+3d=61

(4d+3d)+(−2)=61(Combine Like Terms)

7d+−2=61

7d−2=61

Step 2: Add 2 to both sides.

7d−2+2=61+2

7d=63

Step 3: Divide both sides by 7.

7d7=637

d=9

Step-by-step explanation:

first you add the 4d and the 3d then you subtract 2 from both sides and then you get 7d =59 . then you divide 7 from both sides and get d=52 and thast your final answer

Solution:

Step-by-step explanation:

The formula that is used to calculate the perimeter of  a square is:

Where "s" is the side lenght the square.

Knowing that Xin used  20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

Then, you can susbtitute values into the formula :

Finally, you must solve for "x" in order to find its value.

This is:
