Question

Solve for w in P = 2w + 2l, if P = 38 and l = 12.

Answer 1

normal variables?

Answer 2

38 = 2w + 2*12
38 = 2w + 24

Can you do now?

Answer 3

I jusr substituted the values of P & l in the equation

Answer 4

*just

Answer 5

Yeah

Answer 6

ok

Answer 7

did you get the answer?

Answer 8

almost

Answer 9

what did you get?

Answer 10

is it 100

Answer 11

How?

Answer 12

Remember, just move the ones without letters to the one side and then operate on them

Answer 13

38 times 2 + 24

Answer 14

38 = 2w + 24

Did you understand how i got this?

Answer 15

yes

Answer 16

2*24

Answer 17

Now we have to find w ,

so we subtract 24 from both sides

Answer 18

then move it over

Answer 19

14 and 0

Answer 20

so we is 14

Answer 21

we have to isolate w


38 = 2w + 24

subtract 24 from both sides
38 -24 = 2w + 24 -24

14 = 2w

Now we divide both sides by 2

14/2 =2w/2
14/2=w

so w is?
