First, expand the equation:
10x + 20 = 5x + 40
Now, isolate the variables:
10x - 5x = 40 - 20
Add or subtract:
5x = 20
Divide both sides by 5:
x = 4
There you have it!
10x + 20 = 5x + 40
Now, isolate the variables:
10x - 5x = 40 - 20
Add or subtract:
5x = 20
Divide both sides by 5:
x = 4
There you have it!
