1) Solve the equations 97x^2 = 10x + 15 and 2x + 1x = 1. 2) Solve the equations 6/7 - 5/2 = -j and 94 - 6 = -k. 3) Solve the equations 98 = -x, 58y - = +, and m - 6 = 10 - 3m. 4) A coffee maker originally priced at $x was discounted $20. The customer paid $50, so the original price was $x = $50 + $20 = $70. 5) If half a number + 5 is 11, then half the number is 6, so the number is 12.
