Find the solution to this system: Equation 1: 5x – 2y = -11 (2)
Equation 2: -2x + 5y = 17
Step 1: To create x-coefficients that are additive inverses,
Equation 1 can be multiplied by (2
Multiplying Equation 2 by will create
additive inverses for the x-coefficients.

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label?
