Question

given △def≅△jkl, find the value of x.

Explanation:

Step1: Identify corresponding sides

Since $\triangle DEF\cong\triangle JKL$, corresponding sides are equal. Side $EF$ corresponds to side $JL$. So, $5x - 3=22$.

Step2: Solve the equation for x

Add 3 to both sides of the equation: $5x-3 + 3=22 + 3$, which simplifies to $5x=25$. Then divide both sides by 5: $\frac{5x}{5}=\frac{25}{5}$, so $x = 5$.

Answer:

$x = 5$
