5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94

The solutions to the quadratic equation are: x = -1 and x = 6
y = 5x - 4 Substitute 6 in for y; then solve for x: 6 = 5x -4 10 = 5x 2 = x So, the x-coordinate is 2.
x equals 6 5 times 6 equals 30
If you mean: 5x/7 -6 = x then x = -21
If -4 + 5x = 6, 5x = 6 +4 = 10 or x = 2.
5X+6=8X move 5x to the other side 6=8X-5X 6=3X then solve for x 6/3 = X 2 = X so X = 2 is the answer
5x - 4 = 3x + 6 5x - 3x = 6 + 4 2x = 10 x = 5
x2 - 5x - 6 = x2 - 6x + x - 6 = x(x - 6) + 1(x - 6) = (x - 6)(x + 1)
If x=6 and y=8, then [ 5x + 8y ] = 5(6) + 8(8) = 30 + 64 = 94
5x + y = 6 so that y = 6 - 5x Also x +2y = 1 so that x + 2*(6-5x) = 1 or x + 12 - 10x = 1 => 9x = 11 or x = 11/9 and then y = 6 - 5x = 6 - 55/9 = -1/9
6x-x+15-9= 6x-x=5x 15-9=6 5x+6=0 5x=-6 x=-1.2

x2 + 5x =6 x2+5x -6 = 0 (x+6)(x-1) = 0 x+ 6 = 0 x = -6 x-1 = 0 x = 1
2x - 5x = -6 -3x = -6 3x = 6 x = 6/3 x = 2 By Mohammed Arafat
