Find all possible solutions for x and y such that △ABC is congruent to △DEF. △ABC: sides of length 19, 25, and 3x − 3.
△DEF: sides of length 25, 15, and 5 − y.

△ABC ≅ △DEF when x is ___ and y is ___.

For each proportion find the unknown number x 1/5/8=×/15

Given abcd ac=38 and ae=3x+4 find the value of x

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
