y=4
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .
36..thats very simple..lol
Do a bit of rearrangement: 1: 10x + 2 = 8y; 2: 8y = 59 - 9x so 10x + 2 = 59 - 9x so 19x - 57 making x = 3 and y is therefore 4.
-8y+9=18y-4Add 8y to both sides.9=26y-4Add 4 to both sides.13=26yDivide 13 by 26.1/2=y or 0.5=y
The standard form is 3x - 8y - 4 = 0
The standard form is 3x + 8y + 4 = 0
y2 +8y + 16 = 0 can factor to (y+4) (y+4) = 0 so y+4 = 0 so y = -4
y=4
x = 2, y = 84x + 8y= 4(2) + 8(8)= 8 + 64= 72
2xy - 4x plus 8y - 16 equals x plus 4 in parentheses multiplied by 2y minus 4 in parentheses. So, the factors are ( x + 4) and ( 2y - 4) .

x - 5y = -4 x + 8y = -4 The first equation gives x = 5y - 4 SUBSTITUTE this value for x in the second equation: (5y - 4) + 8y = -4 Simplify: 13y = 0 so that y = 0 Then x = 5y - 4 gives x = -4
5y - 4 + 3y = 12 Combine like terms: 8y - 4 = 12 Add 4 to both sides: 8y = 16 Divide both sides by 8: y = 2
Yes because the slope or gradient are the same 4/3
