Exactly (2y + 4) .

5y-2y= 3y+2 5y-2y-3y= 2 0y= 2
x+2y = 2 2y = -x+2 y = -0.5x+1 Therefore the slope is -0.5 and the y intercept is 1
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
2y=4x+1 sp y=2x+1/2 so the slope or gradient is 2
x2 + 2y = 52 + 2*2 = 25 + 4 = 29
2y(x+2)=
The equation can be simplified to show a value of Y in terms of X. 3X + 2Y +2 = 4Y + 4 3X + 2 = 2Y + 4 3X -2 = 2Y and 2Y = 3X - 2 means that Y = (3/2 X) -1
y=2.5 and x=5
No 2y-3 is not equals y plus 2AND how old are u?

4y+2 = 2y+6 4y-2y = 6-2 2y = 4 y = 2
2x + 2y=-2 (Dividing it by two)x+y=-1 (By transposition)x=-y-1
2y+26 = 28 2y = 28-26 2y = 2 y = 1
(A) 3x + 2y = -2 (B) 6x - y = 6 (A) + 2(B): 3x + 2y + 12x - 2y = -2 + 12 or 15x = 10 or x = 2/3 substitute this value of x in (A) 2 + 2y = -2 2y = -4 and y = -2 Answer: x = 2/3, y = -2
