Question

which equation would you use to solve for x? *
solve for x. (just put the number!!!!) *

Explanation:

Step1: Use the property of parallelogram

In a parallelogram, opposite sides are equal. So, \(5x - 9=3x + 11\).

Step2: Solve the equation for \(x\)

Subtract \(3x\) from both sides: \(5x-3x - 9=3x-3x + 11\), which simplifies to \(2x-9 = 11\).
Add \(9\) to both sides: \(2x-9 + 9=11 + 9\), so \(2x=20\).
Divide both sides by \(2\): \(x=\frac{20}{2}=10\).

Answer:

The equation is \(5x - 9=3x + 11\) and \(x = 10\).
