Question

1)make x the subject of formula

Y = 6x + 11
2) make b and h the subject of formula
A =

`(1)/(2) bh`
​

Answer 1

o 1)

`Y= 6x + 11 \\ \\ 6x = Y - 11 \\ \\ x = (Y - 11)/(6) \\ \\ x = (Y)/(6) - (11)/(6)`

___o__o__

o 2)

`A = (1)/(2) bh \\ \\ bh = A / (1)/(2) \\ \\ bh = A * 2 \\ \\ bh = 2A`

`b = (2A)/(h)`

`h = (2A)/(b)`
