Identify Equation: We have the equation:−3h=15Identify the equation after substituting h=−5.Substitute −5 for h in −3h=15.Equation: −3(−5)=15
Substitute h: Simplify −3(−5).−3(−5)=15Multiplying −3 by −5 gives us 15, since the product of two negative numbers is positive.
Simplify Expression: We found: −3(−5)=15Is h=−5 a solution to the equation −3h=15?For h=−5, the equation becomes 15=15, which is true.So, h=−5 is a solution to the equation −3h=15.
