this is how i worked it out and i keep gettin a decimal:
4x+(9-3x)=8x-1
4x+9-3x=8x-1
3x
1x-9=8x-1
-1x
-9=7x-1
(-9)
7x=8
1.1428571
4x + (9 - 3x)= 8x - 1
1x + 9 = 8x - 1
-7x = -10
x = 10/7
x = 1.43
21=
To solve the equation 4x + (9 - 3x) = 8x - 1, you can follow these steps:
1. Begin by distributing the negative sign to the terms inside the parentheses:
4x + 9 - 3x = 8x - 1
2. Combine like terms on both sides of the equation:
(4x - 3x) + 9 = (8x - 1)
x + 9 = 8x - 1
3. Move all the terms with x to one side of the equation by subtracting x from both sides:
x - 8x + 9 = -1
4. Combine like terms again:
-7x + 9 = -1
5. Isolate the variable term by moving the constant term to the other side by subtracting 9 from both sides:
-7x + 9 - 9 = -1 - 9
-7x = -10
6. Divide both sides of the equation by -7 to solve for x:
x = (-10) / (-7)
x ≈ 1.4285714285714286
Upon solving, the value of x is approximately 1.4285714285714286.
