Katy is solving the linear system below by substitution.
2x + y = 7
3x - 2y = -7
Which of the following would be a step in
solving the system?

Aci is desired for the true average stray-load loss μ (watts) for a certain type of induction motor when the line current is held at 10 amps for a speed of 1500 rpm. assume that stray-load loss is normally distributed with σ = 2.3. (round your answers to two decimal places.)
