x = 0 and y = 4
(-5, 2)
The equation is [ 5y = 35 ].The solution to the equation is [ y = 7 ].
5y + x = 0 subtract 5y from each side, then x = -5y
18y+5y+48+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
That equals 2xy + 3y which factors to y(2x + 3)
5y + 7 = 25y = -5y = -1
2x + 5y = 2-3x - y = -3from the second equation:-y = -3 + 3xy = 3 - 3xsubstitute this value in the first equation:2x + 5(3-3x) = 22x + 15 - 15x = 2-13x + 15 = 2-13x = 2 - 15-13x = -13so, x = 1Now, solve for y :y = 3 - 3xy = 3 - 3 (1)y = zero
x = 0 and y = 4

3X = 15 + 5y does not have a single answer. The answer forms a line on the Cartesian plane. In order to reach a single solution you must have two equations when there are two unknowns.
The equation is [ 5y = 35 ].The solution to the equation is [ y = 7 ].
5y + x = 0 subtract 5y from each side, then x = -5y
