Answer:
6
Step-by-step explanation:
The value of b that makes the two lines identical is the opposite of the y-intercept of the line.
y = 6x -6 . . . . has y-intercept = -6
The value of b is the number in the term -6, so is 6.
58 + (x+9) + (2x-8) = 90
(x+9) + (2x-8) = 32
3x + 1 = 32
3x = 31
x = 31/3
