Solve this system
2x-4y=14
3y+5x=9

x=3, y=-2

Step-by-step explanation:

If 2x-4y=14, then we know that 2x=14+4y.  This means that x=7+2y.  If we substitute this into the next equation we get: 3y+(35+10y)=9.  This means that we have 35+13y=9.  If we subtract 35 from both sides we get 13y=-26.  This means y=-2. If you subsitute this in the first equation, we have 2x--8=14.  -- means + so you do 2x+8=14.  This means that x=3.

btw this is my first answer so sorry if its bad.

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
