x=7
x = -1.2, y = -3
172=x
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
5x + 9 = 4Subtract 9 from each side:5x = -5Divide each side by 5:x = -1
x = -1.2, y = -3
172=x
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
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
9x = 60x = 60/9 = 6 2/3 (or 6.67)
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.
5x = 4x + 9 x = 9
-.6x+.5x+9=-3 -.1x=-12 x=120
