given m||n, find the value of x. ??

Step-by-step explanation:
6x - 10 = 7x - 30
6x - 7x = -30 + 10
-x = -20
x = 20°
Value of x is 20°
Answer:
x = 20
Step-by-step explanation:
Given m||n meaning the lines are parallel: Two angles are alternate exterior angles and so their measure is same
7x - 30 = 6x - 10 export like terms to the same side of equation
7x - 6x = 30 - 10
x = 20
