The solution of the given equation x =11
Step-by-step explanation:
Given equation 34 - 5x = -21
<u>Step :-(a)</u>
Given equation 34 - 5x = -21
Subtracting '34' on both sides , we get
34 - 5x -34 = -21 -34
<u>Step:-(b)</u>
on simplification , we get
-5x = -55
<u>Step:-(c) </u>
Dividing ' -5' on both sides , we get
Cancellation '-5' on both sides , we get
x = 11
<u>Step :-(d)</u>
The solution of the given equation x =11
