Question

question 4 of 10 given ☐sale, solve for x. 3x + 4 5x - 6 3 3 o a. 5 o b. 1 o c. 7 o d. 3

Explanation:

Step1: Recall property of parallelogram

In parallelogram SALE, opposite - sides are equal. So, \(SE = AL\).

Step2: Set up the equation

We have \(3x + 4=5x - 6\).

Step3: Solve the equation for \(x\)

First, subtract \(3x\) from both sides: \(3x+4 - 3x=5x - 6-3x\), which simplifies to \(4 = 2x-6\).
Then, add 6 to both sides: \(4 + 6=2x-6 + 6\), getting \(10 = 2x\).
Finally, divide both sides by 2: \(\frac{10}{2}=\frac{2x}{2}\), so \(x = 5\).

Answer:

A. 5
