Sagot :
I'm going to assume that you want us to figure out what the number is for you.
You said: 2x + 5 = 45
Subtract 5 from each side:
2x = 40
Divide each side by 2 :
x = 20
You said: 2x + 5 = 45
Subtract 5 from each side:
2x = 40
Divide each side by 2 :
x = 20
the answer is 20 which I calculated from the equation of 2x+5=45
