It is 25/3 + 3y.
(3y - 5)(y + 5)
So 1. 4x + 3y = 33 2. x = -4y - 25 Two linear equations (degree one polynomial) are likely to be consistent. If you have some knowledge with matrices, using Gaussian Elimination it can be done easily. I will assume that knowledge is not available. It is known that x and y are related in a way such that both equations are satisfied, in particular x = -4y - 25. so 4x is namely 4(-4y - 25) and 4x + 3y = 4(-4y - 25) + 3y which is 33. Simplify the single variable polynomial y and solve for y. It should be an easy way of rearranging things. For the matrix method, post in discussion.
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
34
3y+5=y-25 2y=-30 y= -15
(2,7)
If you mean: 5x+2y+x-3y then it is 6x-1y
It is 25/3 + 3y.
(3y - 5)(y + 5)
Solve the equations by moving the variable to one side : 7y + 11 = 3y + 25 (subtract 3y from each side) 4y + 11 = 25 (subtract 11 from each side) 4y = 14 Y = 3.5
25x-75y+25 = 25(x-3y+1)
25
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
