Answer:
Pretty sure the answer would be x=6
Step-by-step explanation:
The number (x) in: "3 more than twice a number is 15" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by two (same as twice) and then add 3, you get 15.
To solve this, you first write the problem as an algebra equation as follows: 2x + 3 = 15
Then you solve the equation by subtracting 3 from both sides, and then divide both sides by 2. Here is the math to illustrate better:
2x + 3 = 15
2x + 3 - 3 = 15 - 3
2x = 12
2x/2 = 12/2
x = 6
61-34x98+90+21-4
We will put these in parenthesis to make it easier to read, and to mark what needs done first.
61-(34x98)+90+21-4
34x98=3,332
Now that the multiplication is done, we add and subtract.
90+21=111
61-3,332=-3271
-3271+111-4
We can reorder this to make it easier. Plus, we'll subtract -4 and -3271.
111-3275=-3164
