What is the solution of this linear system 3x plus 5y equals -1 2x-5y equals 16?
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)
What the solution of 2x plus 5y equals 16 and 2x plus 3y equals 14?
2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
What is the ordered pair that is the solution to these equations 3x - 2y equals 8 2x plus 5y equals -1?
y=(-1) x=(2)
What is the solution of x if -5x equals 3 plus y?
-5x=3+y x=-1/5y-3/5
8 plus y equals 7 plus 5y?
Oh, dude, we've got some math up in here! So, to solve this thrilling equation, you just need to get all the y's on one side. Subtract 5y from both sides, and you get 3y on the left. Then, subtract 7 from both sides, and you find out y equals -2. Boom, math wizardry at its finest!
3x plus 2y equals 10 2x plus 5y equals 3?
(4, -1)
7x plus 5y equals 2 8x - 9y equals 17?
(1, -1)
What is -6x plus 3y equals -18 -10 plus 5y equals -30 using substitution?
The question is not quite clear, do you mean -6x+3y = -18 and -10+5y = -30? If so then the solution is: -10+5y= -30 5y = -30+10 5y = -20 y = -4 Substitute the value of y into the equation -6x+3y = -18: Answer: x = 1 and y = -4
What is the equation 80 equals 3y plus 2y plus 4 plus 1?
3y+2y+4+1=80 5y+5=80 5y=80-5 5y=75 y=15
