Since there is no "equals" in the question, there cannot be a formula, only an expression.
18 because you add three then subtract three
In math when you are given a negative and a positive number, you should write down the sign of the greatest number and subtract the smaller number from the greatest number. In the problem 3 - 9, three is the positive number, and nine is the negative number. This means you should write down the negative number's sign and subtract 3 from 9, and your answer should be -6.
The best plan for that particular equation would be to first subtract 15 from each side, and then apply the quadratic formula.
Here are the steps: -- Write the equation. -- Subtract 7 from each side of the equation. -- Subtract 4x from each side. -- Divide each side by 5.
First, let's write it out: 2y+23=y+75 1. Subtract y from both sides to get: y+23=75 2. Subtract 23 from both sides to get: y=52 And that's your final answer for y!
a negative minus a negative = a positive. the two negatives put together make a plus sign. example... 5-(-7) = 13

Four plus four plus three?
