Question

tell me my mistake here....
please...​

Answer 1

Answer:

You have done correct till,

(18x - 7)/21 = 3

18x - 7 = 21×3

18x = (21 × 3 + 7)

x = (21×3 + 7)/18

(here was your mistake)

x = (63 + 7)/18

x = 70/18

x = 35/9

If you r doing wrong, try using brackets as you solve

Hope it helps!

Mark me brainliest!

Answer 2

Answer:

hey dude see carefully

after ,18x-7÷21 =3

18x-7=63

18x=70

x=70/18

so from that point u had done the mistake
