what is the value of y when x=2 in the equation y=-4x - 5?
What is the first step in solving the equation x/5 - 9=6?
To find the value of y when x is equal to -3 in the equation y = -x + 9, you can substitute the value of x into the equation and solve for y.
First, replace the x in the equation with -3:
y = -(-3) + 9
Next, simplify the equation:
y = 3 + 9
Lastly, calculate the value of y:
y = 12
Therefore, when x is equal to -3, the value of y in the equation y = -x + 9 is 12.
