Answer:
-10n +17
Step-by-step explanation:
To simplify such an expression, we eliminate parentheses and combine like terms.
Distributive property
The parentheses are eliminated by using the distributive property. The multiplier outside parentheses multiplies each term inside parentheses.
−4(−11+4n)−3(−2n+9) = (-4)(-11) +(-4)(4n) +(-3)(-2n) +(-3)(9)
= 44 -16n +6n -27
Combine like terms
We can group terms with the variable and those without.
= (-16n +6n) +(44 -27)
= (-16 +6)n + 17
= -10n +17
