X plus 3y-2y plus 3y?
X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y
5y plus 4 - 2y equals 9?
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
When x equals 5 and y equals 3 by how much does the value of 3x plus 2y exceed the value of 2x plus 3y?
2. If x=5 & y =3 then: 3x + 2y = 3 x 5 + 2 x 3 = 15 + 6 = 21 2x + 3y = 2 x 5 + 3 x 3 = 10 + 9 = 19 ⇒ 3x+2y exceeds 2x+3y by 21 - 19 = 2. Alternatively: 3x+2y exceeds 2x+3y by: (3x+2y) - (2x + 3y) = 3x + 2y - 2x - 3y = x - y If x=5 & y=3 then this becomes: x - y = 5 - 3 = 2
What is the answer to this math question 3xy-xy-2y plus 5y?
That equals 2xy + 3y which factors to y(2x + 3)
How do you solve y2 - 3y plus 2 plus 3y - 4y - 5?
I don't know whether it's y^2-3y+2+3y-4y-5 or 2y-3y+2+3y-4y-5, so I'll do both.y^2-3y+2+3y-4y-5y^2+(-3y+3y-4y)+(2-5); group them togethery^2+(-4y)+(-3)y2-4y-3OR2y-3y+2+3y-4y-5(2y-3y+3y-4y)+(2-5); group them together(-2y)+(-3)-2y-3
-3 plus 3y equals 2y plus 5?
3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8
What is 2y plus 2 equals 3y plus 3?
y = -1
3x plus 2y equals -3 2x plus 3y equals -2?
(-1, 0)
X plus 3y equals -7 -x plus 2y equals -8?
are you talking about a system of equations where x+3y=-7 -x+2y=-8 if so, then the answer is {2,-3}
X - 3y equals -3 and 6x plus 2y equals -12?
x = 3y - 3 so 6 (3y - 3) + 2y = -12 ie 18y - 18 + 2y = -12 ie 20y = 6 so y = 0.3 and x = -2.1
X plus 3y-2y plus 3y?
X + 3y - 2y + 3y = X + (3-2+3)y = X + 4y
What is 5y equals 9 plus 2y equals?
Solving for y: 5y = 9 + 2y 5y - 2y = 9 3y = 9 y = 9/3 = 3
What type of lines are these x-3y equals -3 and 6x plus 2y equals -12?
perpendicular
What is y if 5y equals 2y plus 9?
5y = 2y+9 5y-2y = 9 3y = 9 y = 3
What is the solution of 3x plus 2y equals 13 and 2x plus 3y equals 12?
x = 3 and y = 2
5y plus 4 - 2y equals 9?
5y + (4 - 2y) = 9 5y + 4 - 2y = 9 3y + 4 = 9 3y = 5 y = 5/3
5x plus 3y equals 17 5x - 2y equals -3?
Multiply the bottom equation by -1
