9x-5x=4x, 7/4=1.75, x=1.75
9x+7
Well, isn't that just a happy little math problem we have here? To find the product of 9x and 5x, you simply multiply the coefficients (9 and 5) to get 45, and then multiply the variables (x and x) to get x^2. So, the answer is 45x^2. Just like painting a beautiful landscape, math can be a joyful experience when you take it step by step.
4x+7=9x+7 -5x=0 x=0
9x + 7 = 5x + 35Subtract 5x from each side of the equation:4x + 7 = 35Subtract 7 from each side:4x = 28Divide each side by 4:x = 7
14x is the sum of 5x and 9x
14x + 3
9 + 5x = -4x + 63 9 + 9x = 63 9x = 54 9x/9 = 54/9 x = 6
x = 5
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
-4
It simplifies to: 12 -6x
