6x - 11 = 3/5y When y = -1 then, 6x - 11 = 3/(5 x -1) = 3/-5 = -3/5 : Add 11 to both sides 6x = 11 - 3/5 = 102/5 : Convert the mixed number to an improper fraction 6x = 52/5 : Divide both sides by 6 x = 52/5 x 6 = 52/30 = 26/15 = 111/15
2x + y = 5 so y = 5 - 2x; This gives x - 3(5 - 2x) = 13 ie x + 6x = 13 + 15 so x = 4 and y must be -3

It is: y = 5x+15

x=1.5 and y=6x so y=6(1.5) y=9

y=6x² is already solved. the parabola will touch the x-axis at x=0.

An equation with tw unknowns, x and y cannot be solved. Two different equations containing x and y and numbers (including 0 as a number). You have here Y = (X x 2) - 6X + 14, which equals 2X - 6X - 14 which equals (-4X) - 14, so Y = -(4X + 14), but you cannot find the values of X and of Y.
6x - 3y = 36 x intercept: If y = 0, then 6x=36 so x=6 y intercept: If x = 0, then -3y=36 so y = -12
6x - 3y = 6 y= 2x + 5 replace 2x + 5 for y into the first equation 6x - 3y = 6 6x - 3(2x + 5) = 6 6x - 6x - 15 = 6 0 - 15 = 6 -15 = 6 False So the system has no solution.
x=4 y=1 Therefore, 6x+5y=? Just substitute, and get 6*4+5*1=29
