Katrina is solving the equation x minus 2 times open paren x plus 3 close paren is equal to 4 times open paren 2 x plus 3 close paren minus open paren x plus 4 close paren Which equivalent equations might Katrina use? Choose two correct answers.

Distribute −2 across (x + 3) to get x − 2x − 6. On the right, distribute 4 and then subtract both terms in (x + 4): 8x + 12 − x − 4, which gives choice D. Simplifying both sides gives −x − 6 = 7x + 8, which is choice A.
