Question

can someone help me learn equations? (for algebra 1.. I have to take a state test so I want to prepare)

Answer 1

if you can show me an example of the types of equations you need to learn then sure

Answer 2

I say this because your algebra 1 may be different to mine

Answer 3

okay here is an example:

-4(x + 10) - 6 = -3(x - 2)

Answer 4

ooo! okay

Answer 5

suppose you have

4+5=9

Answer 6

if I were to multiply both sides by 6 I would end up with

6(4+5)=6(9)

right?

Answer 7

this isnt the equation i posted right?

Answer 8

no it is not

Answer 9

I am starting from the basics, and we will work our way u p

Answer 10

okay yeah i got that

Answer 11

you just added the 6 right?

Answer 12

okay so when we do
6(4+5)=6(9)
this is
\[(6 \times 4) + (6 \times 5)=6 \times 9\]

Answer 13

okay...

Answer 14

so let's show this in a more general form, using algebra

Answer 15

suppose we have

a+b=c
then we multiply it by a number, D we get

D(a+b)=D(c)
Da + Db = Dc

so if I give you


-4(a+6)=-3

can you attempt to solve for a

Answer 16

im not exactly sure how to solve that

Answer 17

-4(a+6)

to multiply this out of the bracket


multiply the first term what do you get?
