4b – 5b = 2

Please help! I can’t remember how to do this

b = -2

Step-by-step explanation:

-- > 4b — 5b = 2

Combine like terms...

-- > -b = 2

Since we can't have a negative variable, just divide by -1.

-- > -b/(-1) = 2/(-1)

Now we have our answer!:

-- > b = -2

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
