Question

2 ( 2 n - 1 ) = - ( n + 7 )

Answer 1

`\huge\boxed{\sf n = -1}`

Explanation:

Given equation:

2(2n - 1) = -(n + 7)

• Distribute

4n - 2 = -n - 7

• Add n to both sides

4n + n - 2 = -7

5n - 2 = -7

• Add 2 to both sides

5n = -7 + 2

5n = -5

• Divide both sides by 5

n = -5/5

n = -1

`\rule[225]{225}{2}`
