Solve for x round to nearest tenth if necessary?
x -4 = -2x + 9
To solve for x in the equation x - 4 = -2x + 9, we need to isolate the variable x on one side of the equation.
Step 1: Move the constant term to the other side of the equation.
Adding 2x to both sides, we get:
x + 2x - 4 = -2x + 2x + 9
3x - 4 = 9
Step 2: Move the variable term to the other side of the equation.
Adding 4 to both sides, we get:
3x - 4 + 4 = 9 + 4
3x = 13
Step 3: Solve for x.
Dividing both sides by 3, we get:
x = 13/3
To round the answer to the nearest tenth, we divide 13 by 3, which is approximately 4.3.
Therefore, x ≈ 4.3.
