Exactly (2y + 4) .

(3, 2)

x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5

x + 2y = x + 2y Y and X aren't compatibles.

-2y=x+8 is the answer

x = 3 and y = 2

y = x + 1

This means that 2y - 3 = 2y + 4 which is not possible.

x+2y = 2 2y = -x+2 y = -0.5x+1 Therefore the slope is -0.5 and the y intercept is 1

(3, 2)

x = 11 - 2y and 14 - 2y. This means that 11 = 14. Is there a typo in the question?

x + 2y = 62y = -x + 6y = -1/2 x + 3

x = -2 and y = 4 (-2,4)

Both of them are equations!The solution is (x, y) = (2, 1).

1

x = -2 and y = 3

3x + 2y = 5x + 2y = 7Subtract (2) from (1) to give: 3x - x + 2y - 2y = 5 - 7→ 2x = -2→ x = -1Substitute for x in (1)3(-1) + 2y = 5→ -3 + 2y = 5→ 2y = 8→ y = 4Substitute for x and y in (2) to check answer:x + 2y = -1 +2(4) = -1 + 8 = 7 as required. Thus:x = -1y = 4

are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}

x=2y-1

x=0 and y=-1

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

x2 + 2y = 52 + 2*2 = 25 + 4 = 29

(-2, ), (0, ), ( ,4) 2 3 2

x+2y-6 = 0 2y=6-x y=3-x/2 the slope is -1/2 the y-intercept is 3
