For the additive inverse you have to flip the sign of the whole problem so 10(x^2 – 7x) becomes –10(x^2 – 7x). For the multiplicative inverse you take the whole problem and put it under 1 in a fraction.
12
194-50=144
144/12=12
B. x=5, y=4
the tiny triangle is 3x smaller so just divide those numbers by three
