In math, y is a commonly used variable, and depending on the calculation, y has a different meaning.
For y - 2y - 3y equals 0, y equals 0.
a = 3 and y = 0
x = y = 0 ?
The y-intercept equals 0.
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
For y - 2y - 3y equals 0, y equals 0.
a = 3 and y = 0
x = y = 0 ?
The y-intercept equals 0.
y = 0x = y + 2plug 0 in for yx = 0 + 2x = 2
0
A pair of simultaneous eq;ns. 3x + y = 4 x + y = 0 Subtract the two eq'ns. This will eliminate 'y' 2x = 4 x = 2 Substitute this value of 'x' into either eq'n for 'y' 2 + y = 0 y = -2 or 3)2) + y = 4 6 + y = 4 y = 4 - 6 y = -2 ( again) . So the answer is ( x,y) = ( 2, -2).
If ( x = 0 ) and ( y = 1 ), then ( xy = 0 \times 1 = 0 ). Therefore, the value of ( xy ) is 0.
y = 0" the answer is YES.
maybe
36
Then y = 0
