Aidan was frustrated that he needed to write so much when solving an equation. He decided to come up with a shortcut for recording his work to solve a new equation. As you look at Aidan's recording at right of how he solved 2x+4=-12 below, visualize an Equation Mat with algebra tiles. Then answer the questions for each step below. A. Check Aidan's solution in the original equation. Is his solution correct? 2x A 4 = -12 B. Plug x= -8 back into the original equation to check if it is true. -4 -4 2 -16 | 2 2. x = -8​
