Please help me with this

solve for y

We know the two angles are equal because they are Alternate Exterior angles. So, we can write the equation:

3y + 53 = 7y - 55

Now solve.

Add 55 to both sides

3y + 108 = 7y

Subtract 3y from both sides

108 = 4y

Divide by 4 on both sides

27 = y

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
