Question

Pls help I don’t understand

Answer 1

distributive property!

3 (2 + x) - 2 (5 -2x)
turns into

6 + 3x -10 + 4x

now combine terms

final answer: -4 + 7x

Answer 2

3(2+n)-2(5-2n)

Mutiply the first bracket by 3

(3)(2)= 6

(3)(n)= 3n

Mutiply the second bracket by -2

(-2)(5)= -10

(-2)(-2n)= 4n

6+3n-10+4n

6-10+3n+4n ( combine like terms )

-4+7n or 7n-4

Answers: -4+7n or 7n-4
