11

Answer 1

Step-by-step explanation:

sorry for the scraches

x=7/3

and it is verified lhs is equal to rhs

Answer 2

Given: 3 (X - 1) + 7 = 11

To find: verify the L.H.S = R.H.S

Step-by-step explanation:

According to question  

L.H.S

$3(x-1)+7=11$

$3x-3+7=11$

$3x+4=11$

$3x=11-4$

$x=7$

$x=\frac{7}{3}$

put $x=\frac{7}{3}$ L.H.S to prove equal to R.H.S

$3(\frac{7}{3} -1)+7=11$

$3(\frac{7-3}{3})+7=11$

$3\times\frac{4}{3} +7=11$

$4+7=11$

$11=11$

proved L.H.S is equal to R.H.S
