5x 4y equals 12 7x-6y equals 40?

(4, -2)


How do you solve the system of equation 5x-4y equals 14 an 7x-4y equals 26d?

7x-4y = 26 5x-4y = 14 Subtract the bottom equation from the top squation remembering that a minus minus is equal to a plus therefore - 4y - - 4y = 0 2x = 12 Divide both sides by 2 to find the value of x: x = 6 Substitute the value of x into the original equations to find the value of y: Therefore: x = 6 and y = 4


5x plus 4y equals 12 7x - 6y equals 40?

Answer for 5x plus y equals 2 5x-3y equals 14?

5x+y = 2 5x-3y = 14 Subtract the bottom equation from the top equation: 4y = -12 y = -3 Substitute the value of y into the original equations to find the value of x: So: x = 1 and y = -3


X plus 2y equals -1 5x - 4y equals 16?

x+2y = -1 and 5x-4y = 16 Solving the simultaneous equations gives: x = 2 and y = -1.5


What is the solution of 4y-x equals 10 3y plus 5x equals -4?

x=-2, y=2


What is the slope given 5x plus 4y equals -2?

5x + 4y = -2Subtract 5x from each side:4y = -5x - 2Divide each side by 4:y = -1.25 x - 0.5In this form, we can look at it and see that the slope of the graph is -1.25and the y-intercept is -0.5 .


10x plus 2y plus 8z-5x plus 4z-4y equals?

10x + 2y + 8z - 5x + 4z - 4y = 10x - 5x + 2y - 4y + 8z + 4z = (10 - 5)x + (2 - 4)y + (8 + 4)z = 5x - 2y + 12z


What is the y-intercept for this linear equation 5x - 4y equals 18?

-4y=-5x+18 is the same equation. Now divide both sides by -4 and you find the y intercept is -18/4 or -9/2


Find the value of 2x-y if 5x-4 625 and 4y-2 256 Is the answer 10 or 11?

11


Solve the system 4x-3y equals 11 and 5x plus 4y equals 6?

5(4x-3y = 11) 4(5x+4y = 6) Multiply the top equation by 5 and the bottom by 4: 20x-15y = 55 20x+16y = 24 Subtract: -31y = 31 y = -1 Substitute the value of y into the original equations to find the value of x: So: x = 2 and y -1


What is the answer to 5x - 4y plus 9y plus x -9 plus 7?

5x-4y+9y+x-9+7 = 5x + x - 4y + 9y - 9 + 7 = 6x + 5y - 2 ■
