To solve 5(2x+4) =15 , first divide each side by

To solve 5(2x+4) =15

We need to remove 5 first

5 is multiplied with 2x+4

To remove 5 we do opposite operation

First divide each side by 5

2x + 4 = 3

Now subtract each side by 4

2x = -1

Now divide by 2 from both sides

so the value of x is

1 and 2
