2x+8 = 6 2x = 6-8 2x = -2 x = -1
2x + 3 = 9xSubtract 2x from each side:3 = 7xDivide both sides by 7:3/7 = x
2x-3=9 so 2x=12 and x=6
If there are no equals you can simplify this by collecting all the x values together and use the addition property of signed numbers. 2x+4x-5x+x=2x; 4+3=7. 2x+7 is the simplified statement.
If 2x + 5 = 11, then 11 - 5 = 2x 6 = 2x 3 = x
3
2x+3 = 7 2x = 7-3 2x = 4 x = 2
4x + 3 = -3 + 2x + 14 2x + 3 = -3 +14 2x + 3 = 11 2x = 8 x=4
2x+3 = -11 2x = -11-3 2x = -14 x = -7
3x+4 = 2x-3 3x-2x = -3-4 x = -7
(3,3)
2x + 3y = 9x = 3, y = 1 therefore 6 + 3 = 9
3x-2 = 2x+3 3x-2x = 3+2 x = 5
2x + 3 = 9x Subtract 2x from both sides: 3 = 7x Divide both sides by 7: 3/7 = x
2x + 3 = x 2x + 3 - 3 = x - 3 2x = x - 3 2x - x = x - 3 - x x = -3
2x+3=9x 3=9x-2x 3=7x x=3/7
2x + 2/3= 5/3 2x= 3/3 2x=1 x=1/2
