Can someone tell me the answer and show me how to find it?

The value of x is 20°

Step-by-step explanation:

Given that angle in a straight line is 180°. Then you can find the value of x:

55° + (6x+5)° = 180°

55° + 6x + 5° = 180

6x + 60° = 180°

6x = 180 - 60

6x = 120°

x = 20°

Answer: when we graph them, they are one line, coincident, meaning they have all points in common. this means that there are an infinite number of solutions to the system. because this system has at least one solution it is considered to be consistent.
