172=x

x = -1.2, y = -3

5x/6 = -9/6Multiply both sides of the equation by 6:5x = -9Divide both sides by 5:x = -9/5

5x-9Substitute 4 in for x5(4)-9=Solve.9-9=0the answer is zero.The answer is not zero you added when you were supposed to multiply so the real answer is 11.

7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

x = -1.2, y = -3

5x/6 = -9/6Multiply both sides of the equation by 6:5x = -9Divide both sides by 5:x = -9/5

7X-1=9+5X. add 1 to both sides 7X=10+5X. Subtract 5X and get 2X=10 divide by 2 and x=5

You want to isolate the variable x, so subtract 9 from both sides 5x = -26 - 9 = -35 Divide by 5 on both sides x = -35/5 = -7

5x - 3 + x - 9 = 5x Bring like terms together of the left side: 5x + x - 3 - 9 = 5x Combine like terms: 6x - 12 = 5x Add 12 to both sides: 6x = 5x + 12 Subtract 5x from both sides: x = 12

5x = 4x + 9 x = 9

9x = 60x = 60/9 = 6 2/3 (or 6.67)

-.6x+.5x+9=-3 -.1x=-12 x=120

8x-10 = 9-5x Therefore: 8x + 5x = 9 + 10 13x = 19 x = 1 6/19. To solve we moved the x's to one side of the equation and the numbers (constants) to the other side. Then we could simplify to solve for the value of x.
