Which properties were used to prove that the expressions 7 x + 4 minus x minus 2 and 6 x + 2 are equivalent? 7 x + 4 minus x minus 2. 7 x minus x + 4 minus 2. (7 minus 1) x + 4 minus 2. 6 x + 2.

john has 55 candy left.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
