5x 2y = 10
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
Multiply the bottom equation by -1
y = 3x 5x + 2y = 44 substitute 3x for y into the second equation 5x + 2(3x) = 44 5x + 6x = 44 11x = 44 divide by 11 to both sides x = 4 y = 3x substitute 4 for x y = 3(4) = 12 So the solution for the system is the intersection point (4, 12).
5x 2y = 10
(3, 2)
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
If: 3x+2y = 5x+2y = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtract the 1st equation from the 2nd equation: 2x = 0 or x = o By substitution: x = 0 and y = 3.5
If: 3x+2y = 5x+2y = 14 Then: 3x+2y = 14 and 5x+2y =14 Subtract the 1st equation from the 2nd equation: 2x = 0 Therefore by substitution the solutions are: x = 0 and y = 7
Multiply the bottom equation by -1
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
5x - 2y = 20Solve for x:5x = 2y + 20x = 2/5y + 4Solve for y:-2y = -5x + 20y = 5/2x - 10Neither equation can be simplified further without one of the variables already being known.
If: 3x+2y = 5x+2y = 7 which is the same as 7 = 7 = 7 Then: 3x+2y = 7 and 5x+2y = 7 Subtracting equations: x = 0 Therefore by substitution: x = 0 and y = 3.5
