4x-(6x-1)<8x+2(x-3)

7/12 <x

Step-by-step explanation:

4x-(6x-1)<8x+2(x-3)

Distribute

4x - 6x +1 < 8x +2x -6

Combine like terms

-2x +1 < 10x -6

Add 2x to each side

-2x+1+2x < 10x-6+2x

1 < 12x-6

Add 6 to each side

1+6 < 12x-6+6

7 < 12x

Divide by 12

7/12 <x

x > 7/12

Step-by-step explanation:

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
