Yes, the expression (3y - 6 - 6) simplifies to (3y - 12), which is not equivalent to (3y). Therefore, (3y - 6 - 6) is not equivalent to (3y).
Yes
To simplify the expression (2x + 3y - 5x^2 - 10y + 7x^2), first combine like terms. The (x^2) terms combine to (2x^2) (from (-5x^2 + 7x^2)), and the (y) terms combine to (-7y) (from (3y - 10y)). Thus, the equivalent expression is (2x^2 + 2x - 7y).
3y = 2x + 15
The quotient of 2x and 3y is expressed as (2x) / (3y). This represents the division of the two algebraic expressions, resulting in a fraction where 2x is the numerator and 3y is the denominator. Thus, the final answer is 2x / 3y.
g(3y) can be any function: it is not defined by the question.
3x-3y?
6
It is equivalent to 3(4x+3y) when factored
Yes
x = 3y x - 3y = 3y - 3y x - 3y = 3y - 3y x - 3y = 0
3y +3y = 6y
3y + 4z + 12y = 3y -3y -3y ------------------------- 4z + 12y = 0 divide everything by 4 z + 3y = 0 -3y -3y z = -3y
The equation for 3y + 3y = -1 is 3y + 3y = -1.
Expression 1: 2x + 5 - 3y Expression 2: 7(2x + 5 - 3y) Expression 3: 7xy(2 + 5 - 3) Expression 4: 7x(2+5+3y)
3(x-y)
3y = 2x + 15
(3y2 - 3y)/(y - 1) = 3y(y - 1)/(y - 1) = 3y
