Answer 1

if anyone could help me with this that would be great Ive done it 2 times and got bad grades both times

Answer 2

multiply both sides by 5 to clear the annoying fraction

Answer 3

the parentheses on the left side and on the right side?

Answer 4

you should get \[2x-15+3x=21\tfrac{1}{4}\] now at least the fractions on the left are gone

Answer 5

yes left and right

Answer 6

okay

Answer 7

now combine like terms on the left, i .e. add \(2x+3x\)

Answer 8

okay 5x

Answer 9

so now we are at \[5x-15=21\tfrac{1}{4}\] add 15

Answer 10

sorry if my spelling or grammer is a bit off im really tired right now :|

Answer 11

what are we adding 15 to

Answer 12

no one here is a grammarian (least of all me)

Answer 13

the math teaches say "add it to both sides" but you really add it to the right to get rid of the -15 on the left

Answer 14

oh ok yes I think

Answer 15

5x = 21 1/4 is left

Answer 16

no

Answer 17

oh ok

Answer 18

you need to add the 15 to the right as well

Answer 19

5x = 36 1/4

Answer 20

\[5x=36\tfrac{1}{4}\]

Answer 21

yeah that
i hate mixed numbers
now divide by 5

Answer 22

divide what by 5 sorry again

Answer 23

5/5 ?

Answer 24

you have \[5x=36\tfrac{1}{4}\] and you want \[x=\text{sommat}\] to get there you have to divide both sides by 5

Answer 25

i.e. \[x=36\tfrac{1}{4}\div 5\]

Answer 26

7 1/4 right?

Answer 27

yup
