Question

find the value of y when x equals 17 5x+8y=29

Answer 1

Hey mate, here is your answer -:)

___________________________

$5x + 8y = 29 \\ \\ on \: putting \: x = 17 \\ \\ 5(17) + 8y = 29 \\ \: \: \: \: \: 85 + 8y = 29 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8y = 29 - 85 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 8y = - 56 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: y = \frac{ - 56}{8} \\ \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: y = - 7$

The value of y is -7

Answer 2

$y = ? \: \: and \: x = 17 \\ > > our \: equation \: is \rightarrow \\ > > 5x + 8y = 29 \\ \color{pink} \: \underline{ putting \: the \: value \: of \: x \: in \: the \: equation} \\ > > \: 5(17) + 8y = 29 \\ > > \: 85 \: + 8y = 29 \\ > > 8y = 29- 85 \\ > > 8y = -56 \\ > > y = \frac{\cancel-56}{ \cancel8} = -7 \:$
