Determine the value of x for which a || b if m∠1=60-2x and m∠5=70-4x

the answer is 5

Step-by-step explanation: 60-2x= 70-4x

-2x=70-60-4x

-2x=10-4x

-2x+4x=10

2x=10

x=10/2

x= 5

step-by-step explanation:

for exempl this   system of equations   y = x - 3

                                                                y = 2x - 5

look   the line : y = x -3     ( red)

                            the line : y = 2x -5 ( bleus)
