Find the value of the variable.

w鈭�20+5w=28

Short Answer

Expert verified

The value of the variable is w=8.

Step by step solution

01

Step 1. Combine the like terms.

First remove all the brackets and combine the like terms w and 5w.

w鈭�20+5w=28w鈭�20+5w=286w鈭�20=28

02

Step 2. Add 20.

To find the value of variable w in the equation 6w鈭�20=28, add 20 on both sides of the equation.

6w鈭�20+20=28+206w=48

03

Step 3. Divide by 6.

Divide both sides of the equation 6w=48by 6 and cancel the common factors of 6 on both sides.

6w6=486w=6脳86w=8

04

Step 4. Verify the value.

In order to verify the value of w, substitute 8 for w into the equation w鈭�20+5w=28.

8鈭�20+5脳8=28鈭�12+40=2828=28True

Hence, the value of the variable is w=8.
