3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
x=3
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
Yes, y = -4x + 3 is a linear equation.
There are four solutions to 9x4 plus 27x3 - 4x2 - 12x equals 0. One of the solutions is x = -3.
y = 4x-3
3+6x = 4x+9 6x-4x = 9-3 2x = 6 x = 3
x=3
5x - 4x = 13 - 3 ie x = 10
5+4x-7 = 4x+3-x 4x-2 = 3x+3 4x-3x = 3+2 x = 5
= 3
4x+9 = 7x+3 4x-7x = 3-9 -3x = -6 x = 2
-4x+3 = 23+6x -4x-6x = 23-3 -10x = 20 x = -2
If 4x + 7 = 3... then x must equal -1
Yes, y = -4x + 3 is a linear equation.
