What is 4x-3(x-2)21?

Answer 1

To simplify the expression (4x - 3(x - 2)21), first distribute (-3) into ((x - 2)):

[ -3(x - 2) = -3x + 6. ]

Now, substitute this back into the expression:

[ 4x - 3x \cdot 21 + 6 \cdot 21. ]

This yields:

[ 4x - 63x + 126 = -59x + 126. ]

So, the simplified expression is (-59x + 126).
