Answer 1

@pooja195 can you help?

Answer 2

Do you know what the first step would be?

Answer 3

add 10?

Answer 4

ok so we have
\[\huge~\rm~4x=2x+10\]
whats next?

Answer 5

divide by 4?

Answer 6

not quite we need to subtract the 2x
\[\huge~\rm~2x=10\]
now we can divide by 2
\[\huge~\rm~\frac{ 2x=10 }{ 2~~=2}\]

Answer 7

wouldnt it be x= 2 ?? and what about 4x?

Answer 8

We subtracted the 2x from 4x because we need to ISOLATE x
\[\huge~\rm~2\div2=?\]
\[\huge~\rm10\div 2=?\]
