Question

question 7 of 10 given parallelogram s a l e, solve for x. e 3 l 3x + 4 5x - 6 s 3 a a. 1 b. 7 c. 5 d. 3

Explanation:

Step1: Use property of parallelogram

In parallelogram SALE, opposite sides are equal. So, $3x + 4=5x - 6$.

Step2: Rearrange the equation

Subtract $3x$ from both sides: $4 = 5x-3x - 6$.
Simplify to get $4 = 2x-6$.

Step3: Solve for x

Add 6 to both sides: $4 + 6=2x$, so $10 = 2x$.
Divide both sides by 2: $x=\frac{10}{2}=5$.

Answer:

C. 5
