Question

Can someone teach me how to solve equations with variables on both sides?

Answer 1

Example?

Answer 2

for example
4(2x - 1) -3 = 9(x - 4)

Answer 3

First, multiply it out so it is easier to see what we have....

Answer 4

what do you mean by multiply out?

Answer 5

Expand the brackets

Answer 6

as n how? i want you to explain how to do that

Answer 7

For example 9(x - 4) is 9x -36

Do you not know how to do this?

Answer 8

ohhh you mean to simplify by distributive property

Answer 9

So do it....

Answer 10

ok soo here
8x - 4 - 3 = 9x - 36

Answer 11

Now the idea is you want the unknown x on one side of the equals and the numbers on the other...

Answer 12

so how would i get it to one side

Answer 13

The way you have probably been taught is to subtract the same quantity from both sides, is that right?

Answer 14

yes

Answer 15

Or you can just look at it and say to yourself there are 9x on the right and 8x on the left so that's x on the right...

Answer 16

Do the same thing with the numbers and you are left with a single equation to solve...

Answer 17

Simple not single...

Answer 18

is the final answer 29 = x?

Answer 19

Ok?

Answer 20

You can (should) always check an answer by substituting back in the original equation-...

Answer 21

ok let me try that

Answer 22

225 = 225

Answer 23

does that mean im right?

Answer 24

Is 225 equal to 225?

Answer 25

yes

Answer 26

srry i feel stupid now
