Question

Упростить выражение 2m+5n-4n-6m+3n+m

Answer 1

2m+5n-4n-6m+3n+m = (2m-6m+m) +(5n-4n+3n) = 4n - 3m

Answer 2

To simplify the expression 2m + 5n - 4n - 6m + 3n + m, we can combine like terms. Like terms are terms that have the same variables raised to the same powers.

Let's group the terms with the same variable together: (2m - 6m) + (5n - 4n + 3n) + m

Now let's simplify each group separately: (2m - 6m) simplifies to -4m (5n - 4n + 3n) simplifies to 4n

So the simplified expression becomes: -4m + 4n + m

To combine the terms with the same variable, we add or subtract the coefficients (the numbers in front of the variables) while keeping the variable the same.

In this case, we have: -4m + m = -3m 4n remains the same.

Therefore, the simplified expression is: -3m + 4n
