This is how I learned:
-2 + 5x = 13
5x + -2 + 2 = 13 + 2
5x = 15
-- --
5 5
x = 3
Then check:
-2 + 5 x 3 = ?
-2 + 15 = ?
13 =13
This is because when you add and subtract integers, adding negative is subtracting.
Subtracting negatives is like adding, but the result is negative. So, when you take
-2 + 2 it equals 0.
How do you solve 4y plus x equals 8
In math problems without punctuation such as brackets, the standard convention in to solve from left to right. Therefore, you would solve the problem 15-3 times 4 plus nine like by three actions. 15-3 equals 12; 12 times 4 equals 48; 48 plus 9 equals 57.
The question cannot be solved because, thanks to shortcomings of the browser that is used for posting questions on WA, there is no equals symbol. I suggest you resubmit using words like plus, minus, equals to get around the browser problems.
-2 plus 5 equals +3
Any positive number added to it's negative is always = 0
You will never succeed in life if you can't solve problems yourself!
