5x - 2y = 20
Solve for x:
5x = 2y + 20
x = 2/5y + 4
Solve for y:
-2y = -5x + 20
y = 5/2x - 10
Neither equation can be simplified further without one of the variables already being known.

3x plus 2y equals 20 and 5x-2y equals 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
How do I solve 5x plus 2y equals 20?
If as a straight line equation: 5x+2y = 20 then y = -2.5x+10 whereas -2.5 is the slope and 10 is the y intercept
What is the equation of the xy-trace for the plane 5x 2y 3z equals 10?
5x 2y = 10
5x-2y equals -3 what is the slope?
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
What is 5x-2y equals 10 in slope intercept form?
5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
3x plus 2y equals 20 and 5x-2y equals 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
How do I solve 5x plus 2y equals 20?
If as a straight line equation: 5x+2y = 20 then y = -2.5x+10 whereas -2.5 is the slope and 10 is the y intercept
What is the y intercept of 5x - 2y equals 20?
write equation in standfrd form y =mx + b where b = y intercept 5x - 2y =20 5x -20 = 2y 5/2 x -10 = y when x = 0 y = -10, the y intercept
What is the x-intercept for this linear equation 5x-2y equals 20?
5X - 2Y = 20 -2Y = -5X + 20 Y = 5/2X - 10 set to 0 and solve for X 5/2X - 10 = 0 5/2X = 10 X = 4 My TI-84 graphs and confirms this
What is the x intercept of 5x - 2y 20?
Assuming you meant 5x-2y=20... 5x - 2(0) = 20 5x = 20 x = 4 X-intercept is 4
What is the equation of the xy-trace for the plane 5x 2y 3z equals 10?
5x 2y = 10
5x plus 2y equals 19 x - 2y equals -1?
(3, 2)
What is the x intercept in this equation 5x-2y equals 20?
5x - 2y = 20The x-intercept of a line is the point where its y-value is 0. When y=0, we get 5x = 20, or x=4. This means the coordinates of the x-intercept on this line are (4,0).
What is the slope of 5x-2y equals 11?
5x-2y=11 -2y=-5x+11 y=(5/2)x - 11/2 Slope is 5/2
5x-2y equals -3 what is the slope?
5x-2y=-3 -2y=-5x-3 y=(5/2)x+3/2 slope is 5/2
What is 5x-2y equals 10 in slope intercept form?
5x - 2y = 10 2y = 5x - 10 y = 2.5x - 5......which is the equation in slope intercept form.
What is the x and y intercepts for 5x plus 2y equals 20?
The x intercept is the point where y = 0, the y intercept is the point where x =0: For the x intercept: 5x + 2y = 20, but y = 0 => 5x + 0 = 20 => x = 20/5 = 4. So the x intercept is at (4, 0). For the y intercept: 5x + 2y = 20, but x = 0 [The rest of the calculation is left as an exercise for the reader.]
