Answer 1

X=11

Explanation:

Answer 2

`x = 11`

Explanation:

Given

Parallel lines A and B

Required

Find x

For A and B to be parallel, then 5x + 9 and 6x - 2 are alternate interior angles

And alternate interior angles are always equal

This means that

`5x + 9 = 6x - 2`

Collect like terms

`5x - 6x = -2 -9`

`-x = -11`

Multiply both sides by -1

`-1 * -x = -11 * -1`

`x = 11`
