Yes
3y = 2x + 15
g(3y) can be any function: it is not defined by the question.
5y+14+y = 3y-7 5y+y-3y = -7-14 3y = -21 y = -7
2x - 3y = 62x = 3y + 63y = 2x - 6y = (2x - 6)/3y = (2/3)x - 2
3x-3y?
6
It is equivalent to 3(4x+3y) when factored
Yes
3xy
x = 3y x - 3y = 3y - 3y x - 3y = 3y - 3y x - 3y = 0
3y +3y = 6y
Expression 1: 2x + 5 - 3y Expression 2: 7(2x + 5 - 3y) Expression 3: 7xy(2 + 5 - 3) Expression 4: 7x(2+5+3y)
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.
3(x-y)
3y = 2x + 15
