Question

1)make x the subject of formula
Y = 6x + 11
2) make b and h the subject of formula
A =
$\frac{1}{2} bh$
​

Answer 1

Answer:

o 1)

$Y= 6x + 11 \\ \\ 6x = Y - 11 \\ \\ x = \frac{Y - 11}{6} \\ \\ x = \frac{Y}{6} - \frac{11}{6}$

___o__o__

o 2)

$A = \frac{1}{2} bh \\ \\ bh = A \div \frac{1}{2} \\ \\ bh = A \times 2 \\ \\ bh = 2A$

$b = \frac{2A}{h}$

$h = \frac{2A}{b}$
