Question

Please help me with this

solve for y

Answer 1

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
