The statement above is the same as the mathematical expression below...

x + 7 = 2x + 3

We want to solve for x in these types of problems. To do so, we must get all of the "x"s on one side of the equal sign and the constants on the other.

7 - 3 = 2x - x
4 = x

Our answer is x = 4.

So, let’s represent the number as n:
n+7=2n+3
Subtract both sides by 3:
n+4=2n
Now by n:
2n=4
Divide:
n=2
The number is 2

Please solve 4.16 (0.2) and show how you did it.
Alex_Xolod [135]
Okay, so how to do it, so the parentheses around the two doesn’t matter, you can times 4.16 and .2 together to get .832, it is fairly easily.
How I got it: 4.16 is on the top of .2, the decimals line up, you add a zero behind the 2 to make it a 20, now you just Times 4.16 by .20 to get .832
