Evaluate 8 - 4.7y - x when y= -1 and x= 2.
substitute in the values for y and x into the equation.so..8 - 4.7(-1) - (2) solve the equation 8 + 4.7 -2 12.7 - 2 10.7
If you substitute the values in to the equation, you will get:8 - (4.7 * -1) - 2 and that will get you to...8 - (-4.7) - 28 + 4.7 - 2= 10.7
