Answer:

=3x+2

Step-by-step explanation:

Let's simplify step-by-step.

6x+1−(3x−1)

Distribute the Negative Sign:

=6x+1+−1(3x−1)

=6x+1+−1(3x)+(−1)(−1)

=6x+1+−3x+1

Combine Like Terms:

=6x+1+−3x+1

=(6x+−3x)+(1+1)

=3x+2

Let's simplify step-by-step.

6x+1−(3x−1)

Distribute the Negative Sign:

=6x+1+−1(3x−1)

=6x+1+−1(3x)+(−1)(−1)

=6x+1+−3x+1

Combine Like Terms:

=6x+1+−3x+1

=(6x+−3x)+(1+1)

tan 31° = 24 / x

x = 24 / tan 31°

x ≈ 39.9
