What is the answer 3x equals 4y-x?
3x=4y-x 4x=4y x=y
-2x-4y plus 5x-7y equals?
Combine like terms: -2x - 4y + 5x - 7y = 3x - 11y -2x + 5x = 3x -4y + -7y = -11y
Simplify 3x plus 2y plus 2 equals 4y plus 4?
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
What is the slope of a line perpendicular to the line whose equation is 3x plus 4y equals 12?
4y= -3x + 12 y = -3/4x + 3 The perpendicular slope is 4/3
What is the solution of this system 3x plus 4y equals 5 x-4y equals 7?
Add the two equations and get 4x = 12 so x = 3 and y = -1
3x plus 2y equals 4 -3x plus 4y equals -10?
(2, -1)
2x plus 3y equals 17and3x plus 4y equals 24then5x plus 7y equals?
2x + 3y = 17 3x + 4y = 24 (2x + 3x) + (3y + 4y) = (17 + 24) 5x + 7y = 41
What is z in the problem 3x plus 4y plus z equals 27?
You do not have enough information to solve this problem. More accurately, you do not have enough information to assign a numeric value to z. However, abstractly, you could say that z=27-3x-4y.
How do you rewrite -3X plus 4Y equals 11?
4y = 3x+11 or as y = 3/4x+11/4
Solve the system of equations 3x plus 4y equals 12 2x plus 4y equals 8?
x = 4 and y = 0
3x plus 2y equals 7 2x plus 4y equals 18?
(-1, 5)
3x plus 2y equals 7 and 2x plus 4y equals 18?
(-1, 5)
3x plus 4y equals 7 2x plus y equals 3?
(1, 1)
What is the slope of the equation 3x plus 4y equals 8?
It is:- 3x+4y = 8 4y = -3x+8 y = -0.75x+2 So the slope is -0.75 and the y intercept is 2
Is the following a linear function 3x plus 4y plus 2 equals 0?
Yes.
What the answer for this 3x plus 4y?
It is: 3x+4y which is an algebraic expression
