It looks like your equations should be:
x = 3y - 5
2x - y = 18
If this is the case, the equations turn out to be a big mess with lots of decimals/fractions.
-2x+3y=-18
x = 12 y = 2 (12,2) satifies the equation
2x - 3y = 6 2x = 6 + 3y 2x - 6 = 3y : 3y = 2x - 6 y = 2/3x - 2
The quotient of 2x and 3y is = 6xy
(10, 2)
2x plus 3y
-2x+3y=-18
2x + 3y = 18 2x - 3y = 20
x = 12 y = 2 (12,2) satifies the equation
There are infinitely many ordered pairs. The coordinates of each of the infinite number of points on the straight line defined by 2x + 6y = 24 (or equivalently, 3y = -x + 12) is an ordered pair that satisfies the requirements.
The list of choices that accompanies the question is really short.2x + 3y + 6z = 54At the y-intercept, 'x' and 'z' are zero.3y = 54y = 18
Convert the equation into the form y = mx + c, where m is the slope (and c is the y intercept) 2x + 3y = 18 3y = -2x + 18 y = -2/3x + 6 Therefore the slope is -2/3.
Dear Questioner its not able to solve two variables for one equation, give one more equation. Thanks
2x/3y
There are an infinite number of solutions to this equation, some of which are (9,0), (12,2), (15,4), (18,6), (21,8)
How do you add 2x plus 3y equals 18 in 5x-y equals 11
9x+3y=-68 -2x+y=18 We are asked to solve with substitution so we first write y=18+2x. Let us substitute this into the first equation. 9x+3(18+2x)=-68 9x+54+6x=-68 15x=-68-54=-122 so x=-122/15 and y =18+2(-122/15)==18+-244/15=270/15-244/15=26/15 So the solution is (-122/15,26/15) which is an ordered pair.
