Question

a) 1 - a = 8
d) 16-C = 11​

Answer 1

Resposta:

a)

$1 - a = 8 \\ \\ 1 - a \orange{ + a} = 8 \orange{ + a} \\ \\ 1 \orange{ - 8}= 8 \orange{ - 8}+ a \\ \\ \\ \\ - 7 = a \\ \\ \green{a = - 7}$

d)

16 - C = 11

$16 - c \orange{+ c} = 11 \orange{+ c} \\ \\ 16 \orange{- 11 }= 11 \orange{- 11}+c \\ \\ \\ \\ 5 = c \\ \\ \green{c = 5}$
