Answer:

If both sides are equal

Step-by-step explanation:

If both sides are equal and are the same in both sides of the equation, than it is a solution.

For instance, the solution for 2x = 4, is x = 2 because 2(2) = 4 is 4 = 4.

What is 300+-50+-75+225

svetoff [14.1K]

In general it's not "good math" to write "+-". One way to rewrite 300+-50+-75+225 more clearly would be 300 - 50 - 75 + 225.

Working from left to right, 250 - 75 + 225

175 + 225 = 400 (answer)
