Find the roots

Find the roots of the algebra expression

n = 3

Evaluate

5 n + 6 + (- 7 n)

To find the roots of the expression,set the expression equal to 0

5 n + 6 + (- 7 n) = 0

Remove the parentheses

5 n + 6 - 7 n = 0

Subtract the terms

Subtract the terms

More Steps

Evaluate

5 n - 7 n

Collect like terms by calculating the sum or difference of their coefficients

(5 - 7) n

Subtract the numbers

- 2 n

- 2 n + 6

- 2 n + 6 = 0

Move the constant to the right-hand side and change its sign

- 2 n = 0 - 6

Removing 0 doesn't change the value,so remove it from the expression

- 2 n = - 6

Change the signs on both sides of the equation

2 n = 6

Divide both sides

\frac{2 n}{2} = \frac{6}{2}

Divide the numbers

n = \frac{6}{2}
