3.2r+14.7=-6.74

Short Answer

Expert verified

The solution for the equation 3.2r+14.7=-6.74isr=鈭�6.7.

Step by step solution

01

.  Separate the variable and constants

Write the original equation and separate the variables.

3.2r+14.7=鈭�6.743.2r=鈭�6.74鈭�14.73.2r=鈭�21.44

02

 Step 2 .  Solve for r

Now, divide both sides of the equation by 3.2.

r3.2=鈭�21.443.2r=鈭�21.443.2r=鈭�6.7

Therefore, the solution of the equation is r=-6.7.

03

.  Check the solution 

To check the solution, write the original equation and substitute the value of r.

3.2r+14.7=鈭�6.74

Now, substitute r=鈭�6.7and check the result.

3.2鈭�6.7+14.7=鈭�6.74鈭�21.44+14.7=鈭�6.74鈭�6.74=鈭�6.74

As the left-hand side is equal to right hand side, this signifies that the solution is correct..
