Question

ddition and subt. x + 15 = 42 y - 24 = 10 18 + m = 50 w - 7 = -12

Explanation:

Step1: Solve \(x + 15 = 42\)

Subtract 15 from both sides: \(x=42 - 15\)
\(x = 27\)

Step2: Solve \(y - 24 = 10\)

Add 24 to both sides: \(y=10 + 24\)
\(y = 34\)

Step3: Solve \(18 + m = 50\)

Subtract 18 from both sides: \(m=50 - 18\)
\(m = 32\)

Step4: Solve \(w - 7 = -12\)

Add 7 to both sides: \(w=-12 + 7\)
\(w=-5\)

Answer:

\(x = 27\), \(y = 34\), \(m = 32\), \(w=-5\)
