Question

what is 4x+4= -(x-9)

Answer 1

okay. im still a little stuck

Answer 2

In order to solve this problem, you'll need to know:

1. Distributive Rule
2. Inverse Operations
3. Basic Algebra

Which are you having trouble with?

Answer 3

distributive rule.

Answer 4

1. Distributive Rule:

a(b+c) = ab + ac

if a = 4, b = 5, and c = 6, then:

4(5 + 6) = 4*5 + 4*6
4(11) = 20 + 24
44 = 44

This means that no matter what the values of a, b, and, c, both sides will be true. Therefore the distributive rule a(b+c) = ab + ac is true.

Answer 5

Let me know if you understand that

Answer 6

It also means that you can use the distributive rule to help solve algebra:

x(4+5) = 4x + 5x
3(2x + 5) = 6x + 15
7(x + y) = 7x + 7y
y(7x + 4) =7xy + 4y

Answer 7

i got it thanks

Answer 8

Okay, so this means you can solve the problem now.

Answer 9

What do you get for x?

Answer 10

By the way, also, for this, you'll need to know these rules:

- x - = +
- x + = -
+ x + = +

Answer 11

Because if you're just distributing a negative

-(2x - 4) = -2x + 4

because -1 x -4 = 4

Answer 12

In algebra - and -1 mean the same thing

Answer 13

so

-(2x - 4) = -1(2x - 4)
