Question

Solve: y= 7/3x-3 and y=11

Answer 1

x = 6

Explanation:

Given

y =
`(7)/(3)` x - 3 and y = 11, thus

`(7)/(3)` x - 3 = 11 ( add 3 to both sides )

`(7)/(3)` x = 14

Multiply both sides by 3 to clear the fraction

7x = 42 ( divide both sides by 7 )

x = 6

Answer 2

Explanation:

`y =(7)/(3)x -3\\\\(7)/(3)x-3=11\\\\`

Add 3 to both the sides,

`(7)/(3)x-3+3=11+3\\\\(7)/(3)x+0=14\\`

Now multiply both sides by 3

`3*(7)/(3)x=14*3\\\\`

7x = 42

Divide both sides by 7

`(7x)/(7)=(42)/(7)`

x= 6
