Question

what value of x will make lines l and m parallel? 3x 4x + 19

Explanation:

Step1: Identify angle - relationship

When lines \(l\) and \(m\) are parallel, the given angles are corresponding angles and are equal. So, \(3x=4x + 19\).

Step2: Solve the equation for \(x\)

Subtract \(3x\) from both sides: \(0=x + 19\). Then subtract 19 from both sides to get \(x=-19\).

Answer:

\(x=-19\)
