John is 5 years older than mary. in 10 years, twice john's age decreased by mary's age is 35, and john's age will be twice mary's current age. find their ages now. if x is mary's age now and y is john's age now, which system of equations could not be used to solve the problem? y = x + 5 and y + 10 = 2x y = x + 5 and 2(y + + 10) = 35 y = x + 5 and 2(y + 10) = x

chicken nugget stir fry

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
