How many solutions does this equation have 2x y-6 5x-3y7?
If you mean: 2x+y = -6 and 5x-3 = 7 then the solutions are x = -1 and y = -4
What is the answer to this equation y equals -2x plus 3?
y=-2x+3 is an equation. It does not have an answer. If the question is "what if y=0?" then the answer is x=3/2.
What equation has a slope of -2?
Technically, since there are an infinite amount of numbers, there are an infinite amount of answers to this question. But if you want a "Y-intercept" form equation, then there are: y = -2x y = -2x + 1 y = -2x + 2 y = -2x + 3 and so forth. y = -2x + 983475686348684322643843268342648
How do you solve y equals x plus 3 and -2x plus y equals -4?
(1) y = x + 3 (2)-2x + y = -4 It is usual to present the equations showing one unknown expressed in terms of the other unknown. This is already the case in Equation (1). Restructuring Equation (2) gives y = 2x -4 (1) y = x + 3 (3) y = 2x - 4 Now subtract Equation (1) from Equation (3) to eliminate y. y - y = 2x - x -4 -3 : 0 = x - 7 : x = 7 Substitute for x in Equation (1) y = 7 + 3 : y = 10
What is 3y-9 equals 2x in y intercept?
To put the equation 3y - 9 = 2x in y-intercept form (y = mx + b): 3y - 9 = 2x 3y = 2x + 9 (add 9 to both sides of the equation) y = 2/3 x + 3 (divide all terms by 3) The y-intercept is the b term in the equation, which in this example is 3.
