What is x and y (use substitution? ) 5x+3y=38 and y=3x+8?

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 =

Which value of m will create a system of parallel lines with no solution? y= mx - 6 8x - 4y = 12
