If x plus y equals 3 and yx equals 2 then y is equal to what?
If x+y = 3 and y times x = 2 then y = 1.
If y equals x and y equals 6-x what is the solution?
y=x y=6-x Set the two equations equal to each other to yield a solution: x=6-x 2x=6 x=3 x=3 will satisfy both equations, that is plugging in x=3 will give the same value for y y=(3)=3 y=6-(3)=3
How do you Substitute x equals y plus 3 into x plus 2y equals 9?
x = y+3 x+2y = 9 => x = 9-2y y+3 = 9-2y 2y+y = 9-3 3y = 6 y = 2 and x = 5
If an equation of variation where y varies directly as x and y equals 15 when x equals 5 find when x equals 19?
y = 3x y = 3*19 = 57
If y varies directly as x and y equals fifteend and when x equals three find y when x equals twelve?
y is directly proportional to x. When y = 15, x = 3 therefore y = 5x When x = 12, then y = 5 x 12 = 60.
