What is 7x +49

Question

can you tell me what is 7x+49 please

Answer 1

For 7x +49, you can also simplify it by having 7(x +7) or if this problem can be change to 7x =49 instead, you divide 7 by both sides and get x=7. I also hope this helps too.

Answer 2

Hi Ximena Alesandra, 

 

Right now, 7x + 49 equals... anything! The value of the expression changes depending on what value x has. For example, if x = 1, then 7x + 49 = 7*1 + 49 = 7 + 49 = 56. But if x = 10, then 7x + 49 = 7*10 + 49 = 70 + 49 = 119. 

 

Maybe the question gave you more information?

For example, if the question said 7x + 49 = 63, you could solve it like this:

7x + 49 = 63 ... subtract 49 from both sides

7x + 49 - 49 = 63 - 49 ... simplify

7x = 14 ... divide both sides by 7

7x / 7 = 14 / 7 ... simplify

x = 2. 

 

I hope that helps!
