5x = 10 - 20 gives 5x = -10 so that x = -10/5 = -2. Substitute this value in the second equation:-5*-2 + y = 9that is 10 + y = 9so that y = -1
For 5x+y=1, you would subtract 5x from each side, so you would get y=1-5x For 3x+2y=2, you would subtract 3x from each side, and then divide by 2. 2y=2-3x y=1-(3/2)x
The question contains two equations:5x - 6y = 15 5x + y = 2 There are no inequalities in the question.
Put in point slope/function form. 5X + 2Y + 3 = 0 5X + 2Y = - 3 2Y = - 5X - 3 Y = - 5/2X - 3/2 slope = - 5/2 ---------------- Y intercept = - 3/2 -------------------------

5x+2x-3y+y = (5+2)x+(-3+1)y = 7x - 2y
If Y=5x + 2 and x is 5 then Y= 5*5 +2, using order of operations, you get Y=25 +2 Y= 27
5x = 10 - 20 gives 5x = -10 so that x = -10/5 = -2. Substitute this value in the second equation:-5*-2 + y = 9that is 10 + y = 9so that y = -1

(5x + y)(25x^2 - 5xy + y^2)
If: x = 7 Then: y = (2*7)+3 = 17 And: 5x+y = (5*7)+17 = 52
No, there are not, and here's why: to solve for this kind of problem, you will need to set both equations equal to each other. This will give you y - 5x + 2 = y - 5x - 3, You can subtract a y and a -5x from both sides, and this will leave you with 2 = -3, which is, of course, an impossibility. There are therefore no solutions to these inequalities.
Y=-1/2(x)
3y = -5x+2 y = -5/3x+2/3 The gradient is -5/3 and the y intercept is 2/3
