4(x + 3) - 5(2x - 1)
= 4x + 12 - 10x + 5
= 4x - 10x + 12 + 5
= -6x + 17
Penjelasan dengan langkah-langkah:
To simplify the expression, let's start by expanding the brackets:
4(× + 3) = 4× + 4(3) = 4× + 12
-5(2× - 1) = -5(2×) - 5(-1) = -10× + 5
Now we can substitute these expanded expressions back into the original equation:
4× + 12 - 10× + 5
Combining like terms, we have:
(4× - 10×) + (12 + 5) = -6× + 17
Therefore, 4(×+3) - 5(2×-1) simplifies to -6× + 17.
