2x + x + 4 +2x = x + 20 5x + 4 = x + 20 5x - x = 20 - 4 4x = 16 x = 4

If: 12 = 2y+x then y = -1/2x+6 So: y = 2x+4 and y = -1/2x+6 which means that they are perpendicular lines

6x + 12x + 2x = 80 20x = 80 x = 4

5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2

4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.

2x + 4 = 14 (subtract 4 from both sides) 2x = 10 (divide both sides by 2) x = 5

2x + 4 = 8Subtract 4 from each side of the equation:2x = 4Divide each side by 2:x = 2

If 4x - 2x + 4 = 10, the solution is 2x + 4 = 10 and x = 3.

If you mean to say (x^2)-2x+4=0 then there is no solution for x because the equation never makes it to 0 If you mean to say 2x-2x+4=0 then there is no solution for x because it is a horizontal line at Y=4

x equals 4
