    two different lines are parallel if their slopes are the same

    3x-5=145 <--- this the setup 3x=15<----add 5 to both sides divide both sides by 3 x=50

    1. The angles are same side interior angles. If they are supplementary, the lines are parallel. 2. The angles are corresponding angles. If the angles are congruent, the lines are parallel. 3. The angles are alternate exterior angles. If the angles are congruent ,the lines are parallel.

    The equation 3x - 5 = 145 is correct.

    3x - 5 = 145 Add 5 to both sides. Then divide both sides by 3.

    ye, then some details follow like the one on this website http://www.mathsisfun.com/geometry/parallel-lines.html but analytically, slopes are the same when lines are parallel

    x = 50 is correct.
