Question

Basic Algebra equation solving:

Answer 1

2x - 5 + 3

Answer 2

what is -5+3=?

Answer 3

HI!!

Answer 4

hey!

Answer 5

-2

Answer 6

there is nothing to "solve" here because you do not have an equal sign
you can compute \(-5+3=-2\) if you like, but solving requires some sort of equality

Answer 7

Oh wait sorry guys! Lol. Its actually : 2x - 5 = 3

Answer 8

lol how did i guess?

Answer 9

add 5, then divide by 2!

Answer 10

Ok, can u draw it out for me?

Answer 11

yhen, please add at both sides 5

Answer 12

you can do it in your head

Answer 13

what is 3+5?

Answer 14

8 lol

Answer 15

oop.ss then add to both sides 5

Answer 16

what is \(8\div 2\)?

Answer 17

4

Answer 18

you win!!

Answer 19

so what is your solution?

Answer 20

yay! but how do u know what to add or subtract to both sides?

Answer 21

\[2x-5=3\\
2x-5+5=3+5\\
2x=8\\
\frac{2x}{2}=\frac{8}{2}\\
x=4\]

Answer 22

x = 4

Answer 23

you know to add 5 because you want to get x by itself, so you have to get rid of that \(-5\) on the left

Answer 24

Got it! omg u guys are so helpful!!! <3

Answer 25

then you get
\[2x=8\] and since \(2\times 4=8\) your answer is \(x=4\)

Answer 26

for example if you ahve this equation:
x+ 5 = -8
then if I subtract 5 from both sides, I get:
x= -13
then the last equation, is equivalent to the original equation.
Please keep in mind that two equations are equivalent if and only f they admit the same solutions
