Answer:

see the explanation

Step-by-step explanation:

we have

m\angle 2+m\angle 5=180^o ----> given problem

we know that

m\angle 3=m\angle 2 ----> equation A (by vertical angles)

If l is parallel to m

then

m\angle 3+m\angle 5=180^o ---> equation B (by consecutive interior angles)

substitute equation A in equation B

m\angle 2+m\angle 5=180^o ----> is proved  

then

5 (u + 1) -<br>7 = 3<br>3 (u - 1) + 2u​
frez [133]

Correct Question:

5 (u + 1) - 7  = 3 (u - 1) + 2u.

Solve for u

Answer:

See explanation below

Step-by-step explanation:

In this given question, we are required to find u.

Given the equation:

5 (u + 1) - 7 = 3 (u - 1) + 2u​

Required:

Solve for u

To find u, first simplify both sides individually.

Simply 5 (u + 1) - 7:

Expand the parenthesis:

5u + 5 - 7

Collect like terms:

5u - 2

<em>Simplify 3 (u - 1) + 2u​:</em>

Expand the parenthesis:

3u - 3 + 2u

Collect like terms:

3u + 2u - 3

5u - 3

Bring both simplified equations together:

5u - 2 = 5u - 3

5u - 5u - 2 = -3

-2 = -3

Since -2 ≠ -3, there is no solution.

Therefore, we can say the equation is invalid.
