The value of y in the equation is y = 9x - 17 / 5
9x - 5y = 17
we have to make y the subject of the formula.
Therefore, the value of y can be found by isolating y in the equation.
The subject of an equation is the variable you are solving for.
your subject is the variable by itself on either the left or right side of the equation.
The variables in the equation are x and y.
Hence,
9x - 5y = 17
add 5y from both sides of the equation
9x - 5y + 5y = 17 + 5y
9x = 17 + 5y
subtract 17 from both sides of the equation
9x - 17 = 17 - 17 + 5y
5y = 9x -17
divide both sides by 5
5y / 5 = 9x -17 / 5
y = 9x - 17 / 5
